AN OPERATIONAL SAFETY RELIEF VALVE MUST BE INSTALLED IN THE DISCHARGE LINE BETWEEN PUMP AND ANY OTHER PIPE FITTINGS. THIS RELIEF VALVE MUST BE SET AT THE RECOMMENDED RELIEF PRESSURE DESIGNATED ON THE PUMP APPLICATION TAG. CATASTROPHIC DESTRUCTION OF PUMP, PIPING, OR PERSONAL INJURY MAY RESULT IF DISCHARGE LINES ARE CLOSED WHEN THE PUMP IS STARTED, OR AFTER THE PUMP IS RUNNING.

Gears, connecting rod bearings and crossheads in all geared piston type pumps are lubricated by splash from lubricant in the crankcase. Crankshaft bearings and pinion shaft bearings in series 1800, 1500, 1600, 1700, 1900, and 2600 pumps are also lubricated from this same oil in the crankcase by splash. Shaft bearings in Series 1550-C, 1654-C, 2000 and 2200 pumps and in pumps with Serial Number 24523 and below are sealed off from the crankcase lubricant by oil seals and run in a separate bath of oil retained in the respective bearing housing.

WARNING -The crankcase is drained after testing pump at the factory. Remove crankcase cover or crosshead guide hand hole cover and fill with sufficient lubricant before starting the pump for the first time.

Quantity and type of lubricant required to fill crankcase to proper level is shown below. For chain and sprocket driven pumps use an SAE 30 high grade mineral oil in Crankcase.

For herringbone gear driven pumps operating in average climates, use SAE 90EP, AGMA 5EP, or AGMA 6EP gear lubricants. Be sure, however, to use an EP lubricant that will not have a corrosive action on Bronze and that it contains rust, oxidation and foam inhibitors. multi-purpose multi-viscosity gear lubricants are UNSATISFACTORY for use in GASO pumps.

For worm driven pumps, use an SAE 140 EP Gear Lubricant. Running temperature of crankcase oil should not exceed 180 degrees Fahrenheit. If higher temperatures occur and mechanical fits are found to be correct the use of a separate oil cooler is recommended. In addition, SAE EP 140 Gear Lubricant should be placed in separate bath bearings on pump where they are standard.

For low ambient temperatures, select an oil with a pour point lower than the lowest anticipated ambient temperature. Consult GASO factory for recommendations when unusual operating conditions exist.

LUBRICATION OF SHAFT BEARINGS IN SERIES 1550-C, 16540C, 2000 and 2200 - (AND FOR PUMPS #24523 AND BELOW) These pumps are equipped with inner oil seals on pinion shaft and crankshaft, so they run in a separate bath of SAE EP 90 Gear Lubricant or SAE 50 high grade motor oil or mineral oil. The correct amount of oil is put into the bearing housings when pump is shipped from factory, but a check should be made to see that none has leaked out or been removed. Proper oil level is even with pipe plug in lower part of bearing housing flange or cover plate.

Pumps with herringbone gears #24523 and up do not have inner oil seals installed for the pinion and crankshaft bearings as standard equipment however, you pump may have these seals installed as special equipment. if your pump has inner oil seals installed, the amount of oil required for the crankcase is as follows:

To check for wear, place a wrench on the top connecting rod bolt and shake the rod parallel to the crankshaft. (The pressure must be relieved from the liquid end of the pump so that the pump"s mechanism is free to move.) If the rod bearing moves without resistance, the bearing may be too loose and need adjusting. If the bearing does need adjusting, remove shims until you cannot shake the rod, then add .005"" shims one at a time until there is a little side movement. Be sure to torque rod bolt nuts to proper value for each adjustment. (NOTE: If you are making this adjustment after having had the crossheads out, be sure that the oil holes in the rod are pointing up. The ""up"" side is indicated by matching numbers stamped on the cap and rod at the split between them. These numbers should be the same on each rod and should be on the top side of the crankshaft.) Turn the shaft by hand and if there is any hard drag or tight spots in the bearing, add another .005"" shim. After this bearing is properly adjusted, loosen bolts a few turns and repeat the above operation on the other bearings. After all bearings have been adjusted, torque all connecting rod bolt nuts back to proper amount. Again turn the pump by hand to check for excessive drag and tight spots. If none, the pump should then be ready for operation.

If the pump cannot be rotated by hand due to the drive being enclosed, the bearings may be completely adjusted by shaking the bearing on the shaft as stated above. Care must be taken not to over-tighten the bearings since they cannot be checked by rotating the pump by hand. When bearings are adjusted by this method, they must be watched carefully for overheating when the pump is put into operation.

Alternatively, plastic gauge strips, found in most parts stores may be used to adjust these bearings. It is usually better to have a bearing a little too loose than too tight. A slightly loose bearing will cause very little trouble because of the slow operating speeds of the pump, but a tight bearing will overheat and the babbitt may melt or pull. with experience, an operator can tell by feel when the bearings are properly adjusted. Normal precautions must be taken to insure cleanliness of parts upon their assembly. All wrenches used in adjusting these bearings are standard wrenches.

Bearings in the crosshead end are bronze bushings. To replace these bushings, remove connecting rod and crosshead assembly from pump. Press out the crosshead pin, and then remove and replace bushing. After the new bushing has been pressed into the connecting rod, it should be reamed for a loose fit on the crosshead pin as follows: .002"" for pumps Series 1500, 1800, and 1700, .0025"" for pumps Series 1600, and .004"" for pumps Series 2600.

Crankcase bearings for Series 1800, 1500, 1600, and 1700 pumps should have an end play in the crankshaft of: .001"" to .003"" for 1800 pumps .002"" to .004"" for 1500 pumps & 1600 pumps .003"" to .005"" for 1700 pumps

This end play is measured when pump is cold to allow for expansion due to heat under operating conditions. Bearings may be adjusted from one side only. To adjust bearings for end play, disconnect connecting rods, remove several shims (more than necessary) from under the bearing housing, tighten up on crankshaft bearing housings until bearings bind slightly when shaft is rotated by hand. Then measure the shim gap with a feeler gauge and add its equivalent plus from .001"" to .003"" of shim (for normal clearance) and tighten up on crankshaft bearing housing cap screws.

Crankshaft bearings for series 2600 Pumps have a .012"" to .013"" pre-load. To get this pre-load, try different thicknesses of shims until a slight drag is felt while rolling the shaft and then remove .012"" to .013"" of shims. When necessary to install new bearing cones on crankshaft, heat them in oil at 280 degrees Fahrenheit for easy installation. Be sure they are firmly against the shoulder on the crankshaft.

Please note: Improper application of heat to these bearings during their installation in GASO pumps will automatically revoke the warranty on the bearings. It is suggested that the procedures outlines above be closely followed when changing bearings. PINION SHAFT BEARINGS - The pinion shaft bearings are self-contained ball or roller bearings and have no adjustment for wear. Their load ratings are far above the load applied and will therefore have very little wear if properly lubricated.

Although pumps may run backwards without adversely affecting operation, always run them faster than 75 strokes per minute or install inner oil seals for pinion shaft and crankshaft bearings.

In worm-driven pumps, the main or ring gear, is of special nickel alloy bronze with internal flange for bolting to center disc of crankshaft. The driving worm and shaft is one piece, of chrome nickel steel, hardened and ground. This worm and shaft is removable through the end of worm case toward the liquid end of pump but it will first be necessary to remove the flexible coupling, stuffing box, and thrust bearing jam nut from other end of shaft. The thrust bearings will slide off when shaft is withdrawn.

Series 1550-C and 1654-C pumps use quadruple row internal sprockets with specially made heavy duty quadruple row chain. The driving pinion shaft and sprocket is one piece with Nitride Hardened sprocket teeth.

The piston rod stuffing boxes in power end of pump are packed at the factory. The purpose of this packing is to wipe the piston rod clean and thus prevent contamination of lubricant in the crankcase and also to prevent loss of oil from the crankcase. Adjust this packing by evenly tightening the packing gland cap screws until leakage is minimized.

Over a period of time, beginning may, 1978, all liquid end bodies for Duplex Piston Pumps were gradually redesigned to accept an O-ring mounted in a bevel at the opening of the valve covers, cylinder heads and stuffing boxes. This re-design allowed the flange of the valve cover, cylinder head, or stuffing box to fit metal-to-metal with the liquid body. Prior to this re-design most of these liquid ends were counter-bored to accept a flat gasket which caused a gap between the flanges of the valve covers, cylinder head, or stuffing boxes and the liquid end. BEFORE YOU REPAIR YOUR PUMP, MAKE A VISUAL CHECK TO SEE WHAT TYPE OF VALVE COVER, CYLINDER HEAD, AND STUFFING BOXES ARE ON THE PUMP.

The list of serial numbers below will serve as a general guide to the first pumps fitted with o-rings, but does not guarantee that your pump has them. You must check your pump before ordering parts for it. The first number is the pump serial number, the second number is the liquid end serial number:

Liquid end stuffing boxes on a new pump must be packaged by the user before the pump is put into service. The necessary packing will be found in small sacks packed in a box with other pump accessories. Standard packing consists of lip type packing rings. These function best when not squeezed up too tight. Special packing sometimes furnished consists of square graphited duck and rubber packing rings. These require more pressure to seal off fluid satisfactorily, but care should be exercised to avoid over-tightening. Good practice is to let packing leak slightly.

Standard pistons for crude oil service consist of cast iron or steel bodies with special patented cast iron porous chrome faced piston rings. Cast iron or steel piston bodies with nylon glass filled piston rings are furnished pumping crude oil products. Cup type pistons are furnished for pumping saltwater and rubber inserted pistons are used for slush and cementing service.

To replace pistons, remove crosshead jam nuts and power end and liquid end stuffing box glands and packing. Remove cylinder heads and pull rod, piston and liner through front of liquid end. Install new pistons, rings or cups is required. Insert pistons on to rod and into liners, oriented with front of piston toward flange end of liner. Install new liner gasket, and slip liner, piston and rod assembly into pump. Be sure to slip packing glands over rod before pushing rod thru power end stuffing box. Run crosshead jam nut onto rod as far as possible, positioned so flat face of nut will bear upon face of crosshead. Run rod into crosshead until jam nut touches crosshead, then tighten jam nut against crosshead. Be sure all mating surfaces are dry and clean before tightening nuts against pistons or crossheads. Note: torque all nuts holding pistons to rod to 7.200 in.-lbs.

Holding liner in place, roll pump one complete revolution to verify that piston is centered in the liner (end of cast iron piston may stroke out of liner), and adjust as necessary by repositioning the crosshead jam nut on the rod. Once centered, install the packing, glands, and cylinder heads. (See instructions for tightening liner set screws below.) Slush type pistons generally require more frequent attention than other types of pistons.

standard liners for crude oil service are cast iron. Liners for saltwater service are corrosion resistant material. Hardened steel liners are recommended for slush pump service. Always use new gaskets when changing liners.

There are four Liner Set Screws with jam nuts in each cylinder head. These are to hold the liner against the liner gasket. When installing cylinder head, back the liner set screws out a little and then tighten all nuts on cylinder head studs first. Be sure to work around the cylinder head from nut to nut until all are tightened evenly. Then tighten set screws against the liner, torque to 2880 in.-lbs. with the exception of Fig. 1849 pumps which are torqued to 2400 in.-lbs. again working evenly. Lastly, tighten the jam nuts on these set screws. Be sure that packing or lead gasket is in the cupped space on underside of jam nut.

Standard equipment for crude oil service consists of hardened and ground steel wing guided valves and seats. Bronze wing guided valves and seats are usually furnished for fresh or saltwater service. Tops of valve stems are slotted so that valve can be rotated in the pump to regrind valve and seat faces with grinding compound. When worn too badly, they can be removed and faced off in a lathe.

Slush pump valves require frequent replacement of rubber inserts due to the very abrasive material being pumped. Valves and seats should be inspected before starting and when finishing any drilling job. When replacing valve seats, clean valve seat and mating taper in liquid end with a cleaner that does not leave an oil film or residue. Wipe with a clean, dry rag.

Note: If the pump is EVER overloaded (loaded above maximum recommended published pressures) or if a stud EVER fails for any reason whatsoever, REPLACE ALL STUDS IN THE LIQUID BODY BEFORE USING THE PUMP AGAIN.

Pumps are equipped with O-Ring gaskets for valve covers, cylinder heads, and stuffing boxes, and with flat fiber gaskets for suction and discharge flanges. Separate lantern rings and ""tattle-tale"" packing is furnished as gaskets for liners in recently manufactured slush fitted pumps, while pumps fitted for other applications are equipped with spacers and flat fiber liner gaskets. Always be sure that all gasket surfaces are smooth and dry and free of any particles which would scratch or otherwise interfere with efficient operation of the gasket.

Piston displacement and recommended working pressure for continuous duty and with various size liners are shown in the current GASO catalog. When pumping relatively incompressible liquids, volumetric efficiency of pump when valves and liners and pistons are in good shape should be from 95% to 96%. If actual output of pump does not equal 95% of displacement figures shown at the respective speeds, cause o£ trouble may be foreign matter lodged under valve, bad valve facing, worn liners, worn piston rings, or blown liner gasket. Too small a suction line may also be cause of shortage. SUCTION LINES -- (REFER TO DIAGRAM)

Flush suction lines thoroughly before starting pump. Always provide ample capacity suction lines to the pump. This is the first requisite when installing a GASO pump. The pump cannot function properly if an inadequate quantity of fluid is furnished it. For suction lines leading directly to the pump, select a size line so that the velocity of the fluid will not exceed 12 feet per second, or one that is two sizes larger than the pump suction connection, whichever gives the slower line velocity. The last to to 15 feet of this line is preferably flexible hose and should always be connected to the pump inlet with an eccentric reducer (with straight portion on top). Always size ""headers"" feeding more than one pump so that the maximum velocity in the header with all pumps running will not exceed 1 foot per second.

NEVER USE PLUG-TYPE VALVES IN A SUCTION LINE. USE FULL OPENING VALVES. Keep the number of turns to a minimum. When turns are required, use long radius ells. In pumping gasoline or light volatile liquids such as butane and propane, design your system so that the positive suction head at the pump is at least 35 pounds per square inch (psi) above the vapor pressure of the fluid. When pumping water or average crude oils, 10 to 15 psi gauge pressure at the pump will usually be sufficient if pump speed does not exceed 54 RPM. If pump is running at higher speeds, provide for a minimum additional pressure of 15 psi at the pump inlet. Always connect to two sides of pumps with multiple suction inlets. This will help insure proper filling of the pump. If unable to connect to two sides, use a properly sized suction stabilizer, mounted and charged according to instructions with stabilizer.

The mud pumps market size is expected to grow at a significant rate during the forecast period. A mud pump is a large, high-pressure (up to 7500 psi), single-acting triplex reciprocating pump used to circulate mud in a well at a specific flow rate (between 100 and 1300 gallons per minute). Instead of a triplex reciprocating pump, a double-acting two-cylinder reciprocating pump is occasionally utilized as a mud pump. Typically, a rig operator keeps two or three mud pumps on hand, one of which is active and the others on standby in case of an emergency. Mud is gathered up with the use of mud pumps, which use suction to circulate the mud from the wellbore to the surface during the drilling process.

Increased demand for directional and horizontal drilling, higher pressure handling capabilities, and some new oil discoveries are the main drivers of this market"s growth. Mud pumps are specialized pumps that are used to transport and circulate drilling fluids and other related fluids in a variety of industries, including mining and onshore and offshore oil and gas. The global energy demand is boosting the market for mud pumps. However, high drilling costs, environmental concerns, and shifting government energy and power laws may stymie industry growth.

Innovation in technology is the key for further growth for example, MTeq uses Energy Recovery’s Pressure exchanger technology in the drilling industry, as the ultimate engineered solution to increase productivity and reduce operating costs in pumping process by rerouting rough fluids away from high-pressure pumps, which helps reduce the cost of maintenance for operators.

The major key player in global mud pumps market are Flowserve (U.S.), Grundfos (Denmark), Halliburton (U.S.), Sulzer (Switzerland), KSB Group (Germany), Ebara Corporation (Japan), Weir Group (U.K), and SRS Crisafulli, Inc (U.S.). Tsurumi Pump (Japan), Shijiazhuang Industrial Pump Factory Co. Ltd (China), Excellence Pump Industry Co.Ltd (China), Kirloskar Ebara Pumps Limited (India), Xylem Inc (U.S.), and Goulds Pumps (U.S.) are among others.

In the drilling business, MTeq uses Energy Recovery"s Pressure exchanger technology as the ultimate engineering solution to boost productivity and lower operating costs in the pumping process by rerouting abrasive fluids away from high-pressure pumps, which helps operators save money on maintenance. The latest trend reveals that regulatory agencies are persuading manufacturers and consumers to choose electric mud pumps over fuel engine mud pumps to reduce the environmental impact of fuel engine mud pumps.

The global mud pumps market is segmented on the basis of type (duplex pump, triplex pump, and others), component (fluid end and power end), application (oil & gas industry and building industry), and Region (North America, Europe, Asia Pacific, and Rest of the World).

Based on type, mud pumps can be segmented as duplex and triplex pumps. Triplex pumps are expected to progress because of the ~30.0% lesser weight than duplex pumps offering similar efficiency. The pump transfers the fluids with the help of mechanical movements.

Based on application, mud pumps market can be segmented as oil & gas industry and building industry. As oil and gas fields going mature, operators must drill wells with large offset, high laterals, widening their applicability by using mud motors, and high-pressure pumps. To fulfill the demand drilling companies increase their mud pumping installation capacity, with higher flexibility. For instance, LEWCO has developed W-3000 mud pump model for oil drilling, which can handle power up to 3000 HP.

Based on region, North America is predominant because of tight oil and shale gas sources, followed by Asia-Pacific due to the increased number of wells in the regions, especially in countries such as China and India due to the rapid urbanization and industrialization. Authorities in countries such as India, China are working on enhancing their production capacities for reducing the import bills, which ultimately help in the growth of mud pumps market.

This market is broadly driven by oil and gas industry as mud pumps are used to move massive amount of sludge and mud at the time of drilling. Countries such as China, Russia, Saudi Arabia, and the U.S. have the largest number of oil wells. The demand for mud pumps will increase with the number of oil wells, across the globe.

This invention relates to apparatus useful in connection with the drilling of wells, such as oil wells, wherein a mud pump is used to circulate drilling mud under pressure through a drill string, down to and around the drill bit and out the annulus of the bore hole of the well to a mud reservoir; the apparatus of the present invention being useful for simultaneously degassing drilling mud and supercharging the mud pump.

In the drilling of deep wells, such as oil wells, it is common practice to penetrate the earth with a drill bit supported on a drill string in the bore of the well being drilled. In order to lubricate the drill bit, protect the well against blowouts, etc., it is conventional practice to circulate mud under pressure through the drill string down to and around the drill bit and up the annulus between the drill string and the bore of the well. Mud flowing from the well is passed through a suitable device such as a shaker, etc., in order to remove drill cuttings, etc., and is then delivered to a mud reservoir, such as a mud tank, for recirculation to the mud pump for pressured injection into the well.

It is also conventional practice to use a mud pump, such as a duplex or triplex mud pump comprising reciprocating pistons mounted in cylinders for pressuring the incoming drilling mud and delivering it to the well bore under pressure. The operation and construction of mud pumps is well known to those of ordinary skill in the art, as illustrated, for example, by the textbook "Mud Pump Handbook" by Samuel L. Collier (Gulf Publishing Company, Houston, Tex., 1983).

It is known, as explained in the Collier handbook, that the efficiency of a mud pump can be significantly improved by supercharging the pump; that is, by delivering drilling mud under pressure to the mud pump inlet to the cylinders containing the reciprocating pumping pistons.

It is also known to remove occluded gasses such as air, methane, etc., from drilling mud before it is delivered to the mud pump as illustrated, for example, by Burgess U.S. Pat. No. 3,973,930, Burgess U.S. Pat. No. 3,999,965 and Burgess U.S. Pat. No. 4,084,946.

Other drilling mud degassing devices are known to the art, such as those disclosed in Phillips et al. U.S. Pat. No. 4,088,457, Brown et al. U.S. Pat. No. 4,113,452, Egbert U.S. Pat. No. 4,365,977, Gowan et al. U.S. Pat. No. 4,397,659, etc.

Mud pumps used for delivering drilling mud under pressure to the bore hole of a well are conventionally of the type wherein a reciprocating piston in a cylinder is used to pressure drilling mud delivered to the cylinder for delivery to the well bore. Normally, two or three such cylinders are used, such pumps being conventionally referred to as duplex and triplex pumps. During each stroke of the piston, the piston is initially accelerated by an appropriate drive means, such as a crank shaft, from a starting position to a midcylinder position, and then decelerated to a final position within the cylinder. This constantly changing rate of motion of a reciprocating piston can result in knocking, cavitation, etc., all of which impair the efficiency of the pump. It is known to use centrifugal pumps, commonly known as superchargers, in order to deliver drilling mud to the inlet of the cylinder under pressure in order to alleviate such problems and improve the efficiency of operation of the pump.

It is undesirable to recirculate drilling mud containing occluded gases to a well bore, and therefore it is common practice to remove a significant portion of occluded gas from the drilling mud before it is recirculated to the mud pump. Normally, separate pieces of equipment that operate independently of each other are used for supercharging the mud pump and for degassing the drilling mud.

It has been discovered in accordance with the present invention that a drilling mud degasser of the type disclosed in the Burgess patents can be modified to simultaneously degas drilling mud and to supercharge the mud pump to which the degassed mud is to be delivered.

This is accomplished in accordance with the present invention through the provision of a device for simultaneously supercharging a mud pump having pistons reciprocably mounted in cylinders while degassing drilling mud to be delivered to said pistons comprising:

vacuum chamber means for continuously accelerating and centrifuging drilling mud under vacuum to thereby substantially completely remove occluded gas from the drilling mud,

a first conduit interconnecting said vacuum chamber with a drilling mud reservoir for delivering drilling mud to be degassed to said vacuum chamber means,

a first valve controlled branch conduit interconnecting said second conduit with said drilling mud reservoir for delivering drilling mud to said drilling mud reservoir when the pressure in said second conduit exceeds a predetermined value, and

a second branch conduit containing normally closed flow control means interconnecting said second conduit with said first conduit and said drilling mud reservoir operable on loss of pressure in said second conduit to permit flow of drilling mud directly from said drilling mud reservoir to said second conduit.

Referring now to the drawing, there is shown a supercharging drilling mud degasser 10 of the present invention which comprises a degassing chamber designated generally by the number 12, a power source such as an electric powered motor or a hydraulically powered motor designated generally by the number 14, a vacuum blower such as a regenerative vacuum blower, designated generally by the number 16, a gear box designated generally by the number 18, an evacuation pump designated generally by the number 20 and a drilling mud chamber designated generally by the number 22.

In accordance with this construction, there is provided a drilling mud degasser of the type shown in Burgess U.S. Pat. No. 4,084,946, housed in a cylindrical pressure vessel 24. The motor 14 is supported on vacuum blower 16 which, in turn, is supported by vacuum motor support 26 and vacuum blower brackets 28. To facilitate movement of the degasser 10, motor handling brackets 30 may be provided on the top of the motor 14 to which the hook of a crane or other appropriate means (not shown) may be attached.

Drilling mud pump impeller 42 is fixed to the centrifuge tube 40 for rotation therewith within the housing 46 of drilling mud evacuation pump 20. Cross braces 48 mounted in the cylindrical vessel 24 support lower stops 50 and upper stops 52 for an annular float 56 that surrounds the slots of the centrifuge tube 40 and partially closes them, such that the free area of the slots will be determined by the relative position of the annular float 56.

A drilling mud inlet 60 is connected to the bottom of the housing 46 for the evacuation pump 20 for the delivery of degassed drilling mud thereto. Drilling mud is delivered to the slotted centrifuge tube 40 by an inlet conduit 62 which preferably terminates inside the housing 46 for the evacuation pump 20. The top of the inlet line 62 is spaced from the bottom of the slotted centrifuge tube 40 so that the rotating centrifuge tube 40 can rotate freely without bearing upon the top of the inlet line 62. The resultant "controlled seepage" of fluid from the inlet tube 62 into the evacuation pump 20 provides a low pressure area for high effeciency scanvenging of occluded gases. Also, there is no need for bearings and seals at the bottom of the slotted centrifuge tube 40.

With this construction there is also provided an outlet line or conduit 66 connected with the discharge side of the evacuation pump 20 and extending through the wall of the cylinder 24 for connection with a suitable first conduit 68 leading, for example, to a triplex pump 70 for injecting drilling mud under pressure into a well penetrating a subterranean formation in order to lubricate the drill bit, protect the well against blow outs, etc., it is conventional practice to circulate mud under pressure through the drill string down to and around the drill bit and up the annulus beteen the drill string and the bore of the well. Mud flowing from the well is passed through a suitable device such as a shaker, etc. (not shown) in order to remove drill cuttings, etc., and is then delivered to a mud reservoir, such as a mud tank 84, for recirculation to the mud pump 70 in the manner described herein for pressured injection into the well.

The first conduit 68 may comprise, for example, a connecting pipe 72 interconnecting the outlet line 66 with the flexible hose 74 which, in turn, is connected to a mud pump inlet line 76. The flexible hose 74, which is provided for ease in alignment, may be secured to the connecting pipe 72 by a clamp 78 of any suitable construction and to the mud pump inlet line 76 by a clamp 80 of any suitable construction.

A second conduit 82 interconnects a drilling mud reservoir such as a mud tank 84 with the inlet conduit 62 leading to the slotted centrifuge tube 40 for the degasser 10.

Preferably, the second conduit 82 is provided with valve means such as a butterfly valve 86 which may be used to close the second conduit 82 when both the drilling mud degasser 10 and the mud pump 70 are to be idled for any appreciable time.

A first branch conduit 88 interconnects the first conduit 68 with the mud tank 84 and contains pressure sensitive control means such as a spring biased relief valve 90 in order to permit drilling mud to recycle from the first conduit 68 to the mud tank 84 when the pressure in the first conduit 68 exceeds a predetermined value.

A second branch conduit 92 interconnects the first conduit 68 with the inlet conduit 62 and the second conduit 82. The second branch conduit 92 contains normally closed flow control means such as a check valve 94 to permit flow of drilling mud directly from the mud tank 84 to the mud pump 70 if the pressure in the first conduit 68 falls below a predetermined value.

During drilling operations, rotation of an appropriate vacuum blower such as a regenerative vacuum blower by the drive shaft 32 for the motor 14 will generate a vacuum in the degassing chamber 12 such that drilling mud sprayed from the slots in the centrifuge tube 40 will tend to impact upon the inner sides of the degassing chamber 12 thereby initiating degassing of the drilling mud fed through the inlet line 62. Rotation of the centrifuge tube 40 will impart upward accelerating rotary motion to partially degassed drilling mud delivered thereto through the line 62 and the resultant spraying of the thus centrifuged drilling mud through the slots in the centrifuge tube 40 will result in a sheet of drilling mud being sprayed onto and impacting on the inner walls of the degassing chamber 12 to thus substantially complete the removal of gas from the drilling mud. The thus degassed drilling mud will flow downwardly past cross braces 48 and into inlet 60 leading through the housing 46 of the evacuation pump 20 where the impeller 42 will repressure the now degassed drilling mud for discharge through the outlet line 66 which is interconnected with a triplex pump 70 by first conduit 68 for supercharging the pump 70, which further pressures the degassed drilling mud for injection into a well bore penetrating a subterranean formation.

In order to prevent the entrainment of drilling mud droplets in the gases withdrawn through the gas evacuation suction pipe 98, a splatter plate 100 is provided in the degassing chamber 12 and a combination of a foam separation impeller 36 with a splatter disk 102 is provided adjacent the top of the degassing chamber 12 so that gas liberated in the vacuum chamber must follow a sinuous path arriving at the upper chamber gas evacuation suction pipe 98.

In accordance with the present invention, the motor 14 is operated such that drilling mud delivered to the first conduit 68 will be at a predetermined appropriate supercharging pressure for the mud pump 70, (e.g. a pressure of about 20 to 30 psig).

The pressure sensitive control means, such as a spring biased relief valve 90, is set to open at a predetermined pressure about 5 to 10 psi higher than the desired pressure in the first conduit 68 so that, if the indicated pressure limit is exceeded, the pressure relief valve 90 will open in order to permit drilling mud to recycle to the mud tank 84.

This will happen if the mud pump 70 malfunctions and also when the mud pump 70 is turned off, as will happen from time to time. For example, it is necessary to turn off the mud pump 70 during drilling operations when a new stand of drill pipe is to be added to the drill string. It is also necessary to turn off the mud pump 70 when the drill string is being withdrawn from the well bore in order to replace the drill bit, while well logging operations are in progress, if it is necessary to "fish" for a piece of equipment lost down the hole, etc. However, if the drilling mud in the mud tank 84 is permitted to remain quiescent for more than a limited period of time, the drilling mud may start to gel and/or to stratify. This problem is conventionally avoided by providing a separate agitator (not shown) for the mud tank 84 in order to stir the drilling mud when the mud pump 70 is idle. However, through the provision of the present invention, there is no need for a separate agitator for the mud tank 84 because recirculation of drilling mud through the first branch conduit 88 will impart a "roiling" motion or agitation to the drilling mud in mud tank 84 to inhibit gelling and/or stratification of the drilling mud while the mud pump 70 is idle.

Loss of pressure in the first conduit 68 can occur in the event of malfunction of the degasser 10 or in the event it is desired to shut the degasser 10 down for a limited period of time. In this event, drilling mud flows directly from the mud tank 84 through the second conduit 82, the second branch conduit 92 and the flexible hose 74 to the mud pump 70 so that the mud pum 70 is not "starved" for drilling mud to be injected into the well.

Piston pumps can be used for low viscosity and medium-flow media (in the range of 80 m³/h). Additionally, pumping solid particles is impossible with this type of equipment because the pump can ensure proper operation only if the seal between the cylinder and the piston is perfect.

For high-pressure uses, you can opt for a plunger pump, they differ from piston pumps in that the seal does not move with the piston, it is fixed and therefore able to withstand...
