1. APPLICATION Ram Bop is a key part of well-control equipment. It’s used for controllingwellhead pressure during well drilling, workovering and testing, etc., effectivelypreventing well blowout and realizing civilized and safe construction. It can be usedfor the following: 1）With proper pipe ram sealing the annular space between casing and drillingstring when there is pipe in the hole. 2）With blind ram, completely sealing wellhead when there is no pipe in thehole. 3）When in emergent condition, the shear ram will cut off pipe in the well andclose wellhead. 4）When the well head is closed, with killing manifold and choke manifoldconnected to the spool and the outlet of the body doing mud circulating, chokingand releasing, well killing and well cleaning, etc.. 5）With killing manifold and choke manifold, effectively controlling bottom holepressure to achieve balance of bottom hole pressure.

Ram BOP has four sealing parts in order to shut off the wellhead effectively.The ram top seal and body seal; the ram front seal and pipe column, body andsealing between the pipe and the ram front seal; sealing between the body and theside door; sealing between the ram shaft and the side door. Procedure of the ram sealing divided into two steps: First the ram shaftaffected by hydraulic oil pushes the ram front seal rubber to press the front part ofsealing distorted. Over compression between the top seal rubber and the bodyseals the top part and accomplishes primary sealing. Second when there ispressure in the well, the well pressure pushes the ram front seal front back part ofthe ram to extrude distoration more deeply, at the same time, well pressure pushesthe ram up against the body seal face, thus making reliable sealing. This is called"well pressure assisting sealing".

The shear ram assembly is consist of top ram block, bottom ram block, topseal, side seal I, side seal II and blade seal. The blade seal is installed into dovetailwith side seal at two sides. The installation into BOP of shear ram assembly is thesame as normal ram without any modify of BOP.

So we need the secondary seal system to treat it emergently. See figure 8. During a well is shut off, if there is liquid flowing out from the seeing hole (at thebottom part of the middle flange), indicating that the seal rings has been damagedand we can know that the seal on well side or the seal on control side is damagedfrom the liquid. At this time, immediately remove the plug of the grease injectionpore, install club-shaped in the pore, and then turn the screw clock wisely with aninner hex wrench to inject the tightened plug, and inject the secondary seal greaseacross the radial hole of the check valve and supporting seal sleeve into thecircular seam so as to achieve the seal remedy.Caution to use secondary seal system:1) To prevent the grease from being solidified after long time, we do not put greasein BOP in factory. And while the BOP is not used, it is also without this grease.Only before the BOP is used in site, put in the grease. And after a well iscompleted and the BOP is inspected and repaired, take out and clean the grease.2) Get special tool ready.3) During working should often notice the following notice hole plug (on it there is alittle hole) if there is liquid flowing out.4) Don’t inject too much grease when seal ring is damaged. Proper inject quantityis that there is no liquid flowing out. Because the secondary seal grease is morefrictional and with granule substance, it impairs the ram shaft when it returns.

Read this section first before BOP installation. Structure, function and cautionhave been introduced in above-mentioned chapters and this section for installation andoperation.

6.1 Installation on the wellhead6.1.1 Preparing works before installation (1) Check weather gaskets of wellhead flange and BOP flange is well or not andsurface of wellhead flange. Protruding is not allowed to exist. (2) Check installed ram rubber sizes to see if it is compliance with drilling tool sizes. (3) Check weather pressure tests are qualified or not.

6.1.2 Installation of ram BOP （1）After tests, every connection bolt is fixed once again avoiding unbalanceddistribution. See the tightening torque of flange bolt from appendix table 2 or 3.

to ensure its proper operation.1) Check BOP is installed rightly or not: lifting ring of body should be installed on the upside; everywhere the connecting bolt diagonal should be in turn tightened equably.2) Inspect oil pipes to see if they are in compliance with BOP switch direction, provide 286~429psi control pressure to test each ram twice (open and close), draining air from the pipes. If ram switch movement is not the same direction as the mark on the hand rod of control platform, reverse the connection pipes.

1) BOP operation must be charged by specialist and professional person. Operators shall be familiar with BOP working principle, specifications and process, and can also operate, repair, maintain and clear troubles. 2) When testing without string in hole, the max close pressure does not exceed 3MPa to prevent rubber from damage. When there is string in the well pressure prohibit closing the blind ram. 3) In case of need to seal the well for a long time, it should use the manual lock device to lock the ram, and hang the label statement on the control console to avoid the mis-operation. 4) After reaching objective interval, the rams should be opened and closed one time every day to see if they are flexible lock in normal condition. After the drill string is pulled out of the well, blind ram open and close test is needed. When there is string in hole, do not close blind ram.

B. Put drill pipe inside BOP and make sure it connected with test platform reliableduring testing pipe ram to avoid being squeezed out from BOP. There is no drill pipeinside BOP during CSO & shear rams.

6.2.2 Operation, inspection and test procedure of shear ram 1) Preparation A. The hydraulic oil pressure of the accumulator of the hydraulic control system should maintain at 19~21MPa (2714~3000psi). B. After be sure that the tool joint and the drill collar are not at the shear position of shear ram BOP, lock the brake system of hoist engine of drill rig. C. Close the annular BOP and half seal ram BOP that are on the shear ram BOP. D. Drain pressure by open the main blowout pipe. E. Install the corresponding drill pipe bull clip at the suitable position (above the rotary table surface) of the drill pipe. Fix it with the drill rig by the wire rope. 2) Operation steps: A. Push the handle of the side valve of the hydraulic system to the “open” position. And let the high oil of the accumulator directly into the manifold. B. Push the handle of the spool controlling the shear ram to the “close” position and do shear drill pipe operation. C. Observe the pressure change of hydraulic manifold pressure gauge. When the ram begins to close, pressure is dropping. When begin to shear, the pressure is rising and maintains. At the moment of snip, the pressure suddenly drops and then rises and maintains. Hereby, we can judge if the shear is successful. D. Manual lock the shear ram BOP. E. Close the side valve of the hydraulic system. Adjust the pressure of remote control panel to the regulated value. 3) Inspection and maintenance After each shear operation, the shear ram assembly should be put out and do total inspection. The inspection items are including: A. Appearance inspection: ☆ There should be no cracks on every part of the blade. The edge of the blade should not have jag and fold. ☆ There is no obvious damage on the rubber. ☆ There should no any defection on the joint surface of the top and bottom blade and seal installation groove of the blade. B. Do NDT on appearance After shear, all machined surface of the shear ram should be done surface

Figure 13 Inspection for shear ram C. Maintenance ☆ The blade part of the shear ram is forbidden welding. ☆ Carefully polish the fold and deformation part of the edge of the blade by the abrasive stick or abrader. Try to keep the original type of the edge of the blade when it was delivered. (The type of the edge of the blade directly affects shear capability.) ☆ Change damaged rubber sealing. If there is light damage on the rubber, it must be changed. D. Management ☆ Set product using files on every set of shear ram & record the usage condition and inspection condition in detail. ☆ According to regulation of API Spec 16A, the effective usage life of the shear ram normally is three times shear operation. Before the production leaves the factory, the shear ram should be test once. Then, the shear ram can be used twice in practical use. (It is forbidden that do shear test in well site rehearse and daily BOP operation.) After the shear ram has been used on the well site, it should be wasted and no longer to use and be changed with new one. The shear ram appearance inspection can satisfy the requirement of NDT after three times shear operation, it can continually be used. But the usage time should not be more twice. 4) Floor test steps for shear ram: A. Install the BOP on the test seat. Connect the open and close hydraulic control pipes with BOP. Connect the high pressure test pump to the test seat or the outlets of BOP.

B. The open, close and well pressure pipes should be least equipped with a pressure sensor respectively. Connect all pressure sensors with data acquisition system for permanent recorders. C. Vertically lift a 4ft long testing drill pipe above the BOP and then put it into the well hole. When shear the drill pipe, pay attention not to shear the joint. D. Set the pressure of the hydraulic control system to 3000psi. In one operation, close ram and shear the drill pipe. The pressure of shear can be got by rapidly pressure change of the moment of shear. E. Rise the well pressure to 200~300psi and maintain 10 minutes and check the leaking condition. It is qualified if there is no leakage. F. Rise the well pressure to the Max. working pressure of BOP - 5000psi and maintain for 10 minutes. Check the leaking condition. It is qualified if there is no leakage. G. Drop the well pressure to 0 and open the ram. Inspect the corrosion condition of the shear ram and rubber condition & make the record. API 16A Test requirement for shear drill pipe

A. Not install ram or put bonnet on open position. Caution: Not to extend ram shaftcontacting body and fix BOP on the ground to avoid leaning as result of center ofgravity excursion due to two side outlets open at same time.

l Prohibit releasing pressure by opening ram to prevent rubber from damage. Before opening ram, check if the manual-lock system kept in unlocking position each time. And after that, check if the ram remaining fully opened to prevent ram from drilling tool bumping. l Keep hydraulic oil clean. l After usage of BOP ram opened fully for easy repair. l Discharge water from BOP after pressure test and before storage. Put ram in full open position and do rust-resisting treatment.

Ram BOP disassembled into the following three main parts: the body assembly, thebonnet assembly, and ram assembly. It is threaded connections between the body and bonnet bolts , at first loosen andpull out the bonnet bolts, then turn off the oil valve, it means to screw the oil valve inthe end, and tighten it , open the bonnet with less than 10.5MPa of hydraulic oilpressure, which carry out the closed rams action, open the bonnet to the limit position,if the ram is not in the open position at this time, the operation to open the ram controldevice for fluid movement, open the ram to a fully open position to prevent the bonnetclosed, if necessary put two timber pads of same size between the bonnet and thebody, , remove the ram assembly from the rear axle of the ram shaft, , notice to protectthe open and close bonnet rod; Care to protect the positioning flange To avoid thebump and abrasion they connect with eight hexagonal screws of M12 between thePositioning flange and the body interior. Piston Rods for opening and Closing Bonnet are link with the body in threaded,there is a wrench flat Close to the body side, pull the bonnet to the near site of body,subject to not affect the operation of wrench, lifting two M30 screws into the screw holeof the bonnet, put a thin steel tape into the hole of The two screw holes, let the slingconnect with the hanging cranes, one end of the sling connect with steel tape, theother end connect with locking shaft seat assembly, the cable car slowly started so thatthe bonnet off the assembly, under the pressure off the piston rod reduced to aminimum, rotate open and close the bonnet rod, its outward spin out. remove the inner hexagon screws M12 with a wrench , the top wire with two M16(tooling) screwed into the positioning flange on the corresponding holes in the top wire,until the positioning flange departure from the body, put the bonnet and positioningflange into a whole load of accessories box, Please pay attention to protect the ramshaft and flange to avoid the bump and bruises.Note: If you turn in the rotation in poor should not be forced the disassembly to avoiddamage to the opening and closing the bonnet with the surface of the piston rod andthe body and the thread of the opening and closing of the piston rod, then should beadjusted to the side of the hanging level, Then try to disassemble; remaining part of thebody assembly, given the total weight can not exceed 2700Kg, please disassemble thetwo blind flange; Put bonnet bolts, blind flanges, bolts, nuts, gaskets and other smallpieces of equipment into small pieces of container. Assembly and disassemblysequence in reverse order, according to maintenance.

BOP shall be cleared completely after every testing at site. Replace damagedparts in time, anoint so as to prevent rust after cleaned ram chamber and ram of bodyand oil connecting thread part by thread grease.

Ram rubber is the key part in a BOP. If damaged, BOP is useless in sealing well.So it is very important to keep it well, and replace it in time if there is damage in sealingsurface.

▲! Caution: Be sure that manual lock device is in the unlocking position. Procedures of ram rubber replacement: 1) Open the ram completely with hydraulic oil. 2) Loose bonnet bolts (Attention: If BOP is installed on the well with pressure, forbid disassembling bonnet bolts.) 3) Take out of the end plug for assembling the oil valve hole. Close the oil valve. Namely, tighten the oil valve to the end. 4) Open the bonnet assembly with hydraulic oil less than 10.5MPa. At the same time, close the ram. Open the bonnet assembly to the limited position and now the ram is at closed position. 5) If the ram is at the open position, open the ram to total-open position preventing the bonnet from closing. If necessary, put two wood squares (same size) between the body and the bonnet. 6) Bring out the ram assembly from the end of the piston. When bring out the ram assembly, pay attention to protect the piston for opening and closing the bonnet, sealing surface of the bonnet preventing from knocking and scratch. 7) When change the ram rubber, pry the top seal, disassemble the face seal and change the new rubber. Assembling order is contrary to disassembling.
