kelly hose drilling definition manufacturer

A large-diameter (3- to 5-in inside diameter), high-pressure flexible line used to connect the standpipe to the swivel. This flexible piping arrangement permits the kelly (and, in turn, the drillstring and bit) to be raised or lowered while drilling fluid is pumped through the drillstring. The simultaneous lowering of the drillstring while pumping fluid is critical to the drilling operation.

Flexible drilling rubber hoses play an important role in petroleum extraction. They should suffer high operating pressure, extreme operating temperature, abrasion and other inferior elements. Our special compounded synthetic rubber has been proven an effective and economical way to reject these problems. All our oilfield drill hoses are manufactured as API 7K or other related specifications.

Steel cable reinforcement loads most working pressure up to 15,000psi. The wires are usually zinc-plating or copper platting to improve steel wire resistant against rust and corrosion. Due to the thick reinforcement, the hoses should be handled or stored in correct way to avoid kicking or crushing. They will substantially decrease their rated operating pressure.

Rotary hose, Kelly hose, cement hose, mud hose, jumper hose and vibrator hose and choke & kill hoses are the most popular oilfield rubber hoses. They convey high-pressure drilling fluid from one place to another. Many end fittings are provided to satisfy different applications. Most end fittings are made according to API standards. Special order is also available.

A rotary/pumper hose is used in oil well drilling. It acts as the crucial instrument in the connection being made between the standpipe and the swivel.

A rotary hose is also used as a means of permitting the kelly to be either raised or lowered through the drilling process while also allowing the drill bit to be raised with the drillstring. For this reason, it is also often referred to as a “kelly hose.”

Rotary hoses also function during the process that allows the drilling fluid to be pumped through the hose when the bit and drillstring are raised and lowered.

This process is imperative in the completion of the drilling process. The drillstring portion of the drilling line and the connection to the rotary hose is thus crucial.

Made of heavy rubber and steel cables the hose is basicly flexible piping that allows the Kelly and the bit and drill string to be raised and lowered while the drilling fluid is pumped through drill string.

lowering the drill string and pumping drilling mud is very important to the drilling process and when these hoses go down or fail in service a entire rig can shut down.

Made of heavy rubber and steel cables the hose is basicly flexible piping that allows the Kelly and the bit and drill string to be raised and lowered while the drilling fluid is pumped through drill string.

Rotary Drilling/Pumper hose is mainly used for conveying water-based or oil-based mud and other fluids in the working temperature of -30 °C to +82 °C.

The reinforcement is made from 2-8 layers of high tensile and high strength spiraled steel wire, making the hose have solid structure and resistant to high pressure.

The cover is made from high quality synthetic rubber, mainly chloroprene rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, aging and sunlight.

A Kelly hose (also known as a mud hose or rotary hose) is a flexible, steel reinforced, high pressure hose that connects the standpipe to the kelly (or more specifically to the goose-neck on the swivel above the kelly) and allows free vertical movement of the kelly while facilitating the flow of drilling fluid through the system and down the drill string.

High-pressure mud hose also called rotary hose, vibrator hose or jumper hose, is used to convey drilling fluid from mud pump to the mud standpipe manifold on the drill floor.

In an effort to prevent kinking, binding or snagging of kelly spinner hoses during the raising and lowering of said hoses together with a rotary hose in oil drilling rigs, it is known to tape the kelly spinner hoses to the rotary hose which provides the drilling fluid. There is a serious defect in this arrangement since the kelly spinner hoses and the rotary hose are used independently in the sense that they are under different pressures at different times. Thus, for example, the kelly spinner hoses will not be pressurized with air when the rotary hose is pressurized with the drilling fluid. Since the pressurization of the rotary hose is typically in the range of from four thousand to five thousand psi, the hose is substantially elongated typically from about six to ten inches. This results in substantial straining of the kelly hoses. By the same token the kelly hoses when they are pressurized, are strained due to the fact they are prevented from moving relative to the rotary hose. Further, these strains have a tendency to rupture the tape leaving the kelly spinner hoses free to move independently which is a serious hazard for rig personnel since, if one of these hoses ruptures or separates from the fittings attached to the kelly swivel it will whip violently incident to the exhausting of the high pressure air through the rupture or the freed end of the hose. All of these problems have been solved by this invention by providing guides for the kelly hoses which attach to the rotary hose and permit the kelly hose and the rotary hose to move freely axially relative to each other while preventing kinking, binding and snagging while the hoses are raised and lowered. In addition, the invention facilitates the installing and disconnecting the kelly spinner hoses. The life expectancy of the kelly spinner hoses is increased, reducing down time.

The invention is a safety guide for kelly spinner hoses in drilling rigs and a plurality of said safety guides in combination with kelly hoses and a rotary hose. Each safety guide comprises a pair of opposed rings, each adapted to receive and guide a kelly spinner hose, and a device for securing the rings to a rotary hose substantially in a plane perpendicular to the axis of the rotary hose. Advantageously, each ring has a rigid integral loop member and the securing device comprises a flexible band passing through said loop members. It is preferred to secure the band to the rotary hose with a buckle. In the combination, a plurality of the safety guides are spaced along the length of the rotary hose, preferably substantially equidistant.

FIG. 3 is an elevational view showing a guide in accordance with the invention in association with the kelly spinner hoses and the rotary hose of the rig of FIG. 1;

Referring to FIG. 1, an oil drilling rig 2 has a derrick 4 having a hoist 6 provided with a lifting hook 8 which is adapted to engage a ring 10 (FIG. 2) attached to a swivel fitting 12 which in turn is connected to a kelly indicated at 16 adapted to connect with a rotary table 18 (FIG. 1). A kelly spinner 20 rotates kelly 16 and is supported by a turn buckle 22 connected to swivel fitting 12.

A rotary hose 26 is connected by a fitting indicated at 28 (FIG. 2) to swivel fitting 12. Rotary hose 26 is connected to a stand pipe 30 which is adapted to deliver a drilling fluid as indicated at 32 (FIG. 1). Kelly spinner hoses 40 and 42 are connected to Kelly spinner 20 and are respectively connected to their delivery pipes 44 and 46 as indicated at 48 and 50 (separated for clarity in FIG. 1, but actually close to fitting 32).

Kelly spinner hoses 40 and 42 are each guided by a plurality of guides 60 in accordance with the invention which are substantially equally spaced along the length of rotary hose 26.

As best seen in FIG. 4, each guide 60 has a pair of opposed guide rings 62 and 64 through which hoses 40 and 42 pass respectively. Guide ring 62 has an integral member loop member 66 which runs substantially perpendicular to a plane through ring 62 and has a relatively narrow opening 68 (FIG. 3). Likewise, guide ring 64 has an integral loop member 72 running substantially perpendicular to the plane of ring 64 and having a relatively narrow opening 74.

A band 78 passes through openings 68 and 74 and around rotary hose 26 to which it is tightly secured by buckle 80. Buckle 80 has a flat plate 82 to which is secured a loop 84 (FIG. 5) and outwardly and downwardly extending opposed fingers 86, 86. The inner end 90 of band 78 passes between plate 82 and loop 84 and between back plate 82 and fingers 86, 86 and is bent back on itself inside of plate 82. Band 78 is then run around rotary hose 26 twice passing through loop members 66 and 72 and between plate 82 and both loop 84 and fingers 86 twice to form two loops indicated at 96 and 98 in FIG. 4 and then outer end 92 is turned back on itself over loop 84 and passed inside of fingers 86, 86 thus securing the rings 62 and 64 to rotary hose 26 (FIGS. 4 and 5).

The guides 60 are substantially equally spaced along hose 26 advantageously at a distance of from about 96 to about 144 inches. It will be seen that since the kelly spinner hoses 40 and 42 are loosely received in guide rings 62 and 64 each of the hoses 40, 42 and 26 can move freely axially relative to each other. Should one of the hoses 40 or 42 become detached from the kelly spinner it will be prevented from dangerous whipping. While a variety of materials may be used to make the guides 60, it is preferred to employ stainless steel for all the parts. The guide rings 62 and 64 are conveniently welded to loop members 66 and 72 as indicated at 100 and 102 respectively in FIGS. 3 and 4.

A kelly hose is a piece of mining equipment. Specifically, it refers to a piece of equipment used in the mining of fluid or semi-fluid resources, such as oil and natural gas. The main purpose of a kelly hose is to allow the drill string to be raised and lowered at the same time that drill fluid is being pumped through it. This is important, as drill fluid is critical to the mining process.

In most cases, a kelly hose is classified as a large-diameter hose. This means that the inside diameter is usually between 3 and 5 inches (about 7.6 cm and 12.7 cm). This wide diameter allows for a significant rate of flow and reduces the likelihood of a blockage occurring in the hose.

The kelly hose must also be able to withstand large amounts of pressure. This applies primarily to the pressure of the fluid flowing through the hose. For this reason, it is often made of highly durable material and is generally reinforced with steel.

In a derrick or drilling rig, the kelly hose connects the standpipe, which is the rigid metal shaft that delivers the mining fluid, to the swivel, which is the piece that supports the weight of and controls the rotation of the drill string. Its purpose is to provide a flexible drilling fluid conduit, as a rigid conduit would be unable to move with the swivel and would therefore disallow movement of the drill string and, subsequently, the bit.

The drilling fluid, sometimes called drilling mud, carried by a kelly hose is critical to operations in several ways. It keeps the bit cool, which helps reduce friction and failure. It also cleans the bit and carries away drill cuttings so they cannot damage the drill assembly. Some varieties are used for additional purposes, such as preventing corrosion and providing hydrostatic pressure. Drilling fluid is not necessarily fluid, but may, in fact, be a solid, liquid, gas or other combined form.

The kelly hose is so named because of its connection with the kelly, the actual mechanical piece that ejects the drilling fluid over the drill string. It may alternatively be called a mud hose or a rotary hose. Failure can occur, despite the rugged construction of the hose. Such failure can lead to damage to the rig or a failure to operate. Failed kelly hoses must be repaired or replaced before mining operations can safely and effectively resume.

n pl: 1. the well cuttings obtained at designated footage intervals during drilling. From an examination of these cuttings, the geologist determines the type of rock and formations being drilled and estimates oil and gas content. 2. small quantities of well fluids obtained for analysis.

n: a wireline used on drilling rigs and well-servicing rigs to operate a swab or bailer, to retrieve cores or to run logging devices. It is usually 9/16 of an inch (14 millimeters) in diameter and several thousand feet or meters long.

n: an expendable substitute device made up in the drill stem to absorb much of the wear between the frequently broken joints (such as between the kelly or top drive and the drill pipe).

v: to place stands of drill pipe and drill collars in a vertical position to one side of the rotary table in the derrick or mast of a drilling or workover rig. Compare lay down pipe.

n: a procedure to ensure that the drilling line wears evenly throughout its life. After a specified number of ton-miles (megajoules) of use, the line is slipped-for example, the traveling block is suspended in the derrick or propped on the rig floor so that it cannot move, the deadline anchor bolts are loosened, and the drilling line is spooled onto the drawworks drum. Enough line is slipped to change the major points of wear on the line, such as where it passes through the sheaves. To prevent excess line from accumulating on the drawworks drum, the worn line is cut off and discarded.

n: a condition wherein shale that has absorbed water from the drilling fluid expands, sloughs off, and falls downhole. A sloughing hole can jam the drill string and block circulation.

n: 1. in drilling, a plastic mixture of cement and water that is pumped into a well to harden. There it supports the casing and provides a seal in the wellbore to prevent migration of underground fluids. 2. a mixture in which solids are suspended in a liquid.

adj: descriptive of a substance whose strength or merit has been exhausted in a process. For example, after a well has been acidized, any acid that remains in the well is said to be a spent acid because its strength has been used up in the acidizing process.

n: a measurement of the electrical currents that occur in the wellbore when fluids of different salinities are in contact. The SP curve is usually recorded in holes drilled with freshwater-base drilling fluids. It is one of the curves on an electric well log. Also called self-potential curve.

v: to thread the drilling line through the sheaves of the crown block and traveling block. One end of the line is secured to the hoisting drum and the other to the drill-line anchor.

n: drill pipe, drill collars, casing, or tubing that has inadvertently become immovable in the hole. Sticking may occur when drilling is in progress, when casing is being run in the hole, or when the drill pipe is being hoisted.

n: a short, threaded piece of pipe used to adapt parts of the drilling string that cannot otherwise be screwed together because of differences in thread size or design. A sub (a substitute) may also perform a special function. Lifting subs are used with drill collars to provide a shoulder to fit the drill pipe elevators; a kelly saver sub is placed between the drill pipe and the kelly to prevent excessive thread wear of the kelly and drill pipe threads; a bent sub is used when drilling a directional hole.

The rotary system includes all of the equipment used to achieve bit rotation. Originally, the main driver in the system of all rigs was the rotary table. The main parts of the rotary system with a rotary table are the swivel, kelly, and drillstring.

The rotary swivel (Fig. 1)serves two important functions in the drilling process. It is a connecting point between the circulating system and the rotary system. It also provides a fl uid seal that must absorb rotational wear while holding pressure. The upper section of the swivel has a bail for connection to the elevator hook, and the gooseneck of the swivel provides a downward-pointing connection for the rotary hose.

The kelly is the fi rst section of pipe below the swivel. The outside cross section of the kelly is square or (mostcommonly) hexagonal to permit it to be gripped easily for turning. Torque is transmitted to the kelly through kelly bushings, which fi t inside the master bushing of the rotary table. The kelly thread is right-handed on the lower end and left-handed on the upper end to permit normal right-hand rotation of the drillstring.

During drilling operations, in every connection, a new pipe is added below the kelly. To avoid premature wear in the kelly’s threads, a kelly saver sub is used between the kelly and the fi rst joint of drillpipe. Kelly cock valves are located on either end of the kelly.

Modern rigs use a topdrive to replace the kelly, kelly bushings, and rotary table. Drillstring rotation is achieved through hydraulic or electric motors. One type of topdrive is shown in Fig. 2

Topdrives are suspended from the hook and can travel up and down the derrick. This will allow drilling to be done with stands of pipes, instead of single joints, which will save considerable time. Comparing with the conventional process, where a new pipe must be added to the drillstring after the length of just one joint has been drilled, using a topdrive system, a new connection will occur only after the length of one stand (two, three, or four pipes) has been drilled.

Range 2 drillpipe is used most commonly. Since each joint of pipe has a unique length, the length of each joint must be measured carefully and recorded to allow a determination of total well depth during drilling operations.

The BHA is the lower section of the drillstring. Even though a BHA may have many different tubulars depending on the complexity of the operation, most of the BHA is composed of drill collars (Fig. 3c). The drill collars are thick-walled, heavy steel tubulars used to apply weight to the bit. The buckling tendency of the relatively thinwalled drillpipe is too great to use it for this purpose. The smaller clearance between the borehole and the drill collars helps to keep the hole straight. Stabilizers (Fig. 4)often are used in the drill collar string to assist in keeping the drill collars centralized. Other types of tubulars used include shock absorbers and drilling jars. In addition, heavyweight drillpipes, a type of drillpipe with thicker walls, are commonly placed on top of the BHA to make the transition between the heavier drill collars and the drillpipes.

Working on a drilling rig is risky business by anyone’s standards. Safety must a matter of paramount concern in order to prevent injuries and accidents.

Workers on drilling and workover rigs may sometimes take matters into their own hands, resulting in safety violations or, worse, injury. And while it is the rig operator’s responsibility to see that they are sufficiently trained and that the workplace is free from hazards, it is vital that every person on a rig site develop a keen sense of safety.

In an effort to help those in the industry adopt a safety first mindset, Grainger, a supplier of MRO products to the oil and gas industry, offers the following guidelines:

Emergency Preparedness OSHA requires emergency response plans for every drilling site, which can vary depending on the rig’s location and layout. Grainger says that an effective plan should always include the ready availability of appropriate emergency and rescue equipment, as well as a program for training and drilling of all supervisors and workers on emergency escape and rescue procedures.

A 27-year-old gas drilling rig worker died on May 23, 2003 from blunt force trauma to the head, neck, and chest during a cleanout operation at the well. At the time of the incident, the victim was working within eight feet of the kelly on the drilling rig floor. Compressed air was used to blow out the conductor pipe, but due to a lack of communication, the compressor was turned on before the valves were prepared to control the flow of debris out of the hole. The excess pressure caused the kelly bushing, drillpipe slips, and debris to be blown out of the rotary table. The victim was struck by these objects and was pronounced dead on arrival to the hospital.

A 27-year-old gas drilling rig worker died on May 23, 2003 from blunt force trauma to the head, neck, and chest after he was struck by the kelly bushing and drillpipe slips. OKFACE investigators reviewed the death certificate, related local news articles, and reports from the sheriff’s office, Medical Examiner, Occupational Safety and Health Administration (OSHA),

The drilling company that employed the decedent had been in business for 33 years and, at the time of the incident, employed 140 individuals. The victim had five years of experience in drilling operations and had worked for this drilling company off and on over that five-year period. However, during this time of employment, he had been working for the employer for only three days. At the time of the incident, the decedent was part of a five-person crew that was working at a gas well site, which had been in operation for three days (Figure 1). The victim was fatally injured during a cleanout operation. The cleanout process is a normal part of drilling operations and involves blowing out mud, water, and debris by pressurizing the well shaft with either air or liquid as the standard cleaning media. The victim had performed the cleanout process many times in the past.

The company did have a comprehensive written safety program in place at the time of the incident. The victim had received formal company safety training and informal on-the-job training specifically relating to cleanout operations. Safety meetings were held regularly, and levels of training were measured by employee testing and demonstration. Two of the five workers at the site had recently joined the crew from other drilling companies; however, they each had years of experience in oil and gas drilling.

At the time of the incident, the rig floor and working surfaces were level and dry; the weather was warm with light to no wind. The victim was working with four other crew members on a gas drilling rig, wearing the necessary personal protective equipment (e.g., steel toe boots, hard hat, eye protection). Prior to the incident, the decedent was assigned the task of driller and was asked to find the bottom of the conductor hole with the kelly (Figure 2). The kelly is used to transmit power (rotary motion) from the rotary table and kelly bushing to the drillstring (Table 1). After unlatching the brake handle, the driller allowed the kelly to free fall to the bottom. The uncontrolled fall caused the kelly to become jammed with debris, such as water, mud, and other material, that had collected in the conductor hole since the time it was originally drilled for the well. As a result, a cleanout operation became necessary. Cleanout procedures involving air or mud drilling fluid are acceptable norms in the oil and gas drilling industry; however, drilling fluid is more commonly used than compressed air.

a long square or hexagonal steel bar with a hole drilled through the middle for a fluid path; goes through the kelly bushing, which is driven by the rotary table

After the kelly became jammed, a senior driller was assigned to take over the brake handle and kelly; however, the decedent remained approximately eight feet away on the rig floor. A newly hired, yet experienced, derrickman had the job of running the air compressor. While the drillers were switching positions, the derrickman realized that he had not started that particular type of compressor in quite some time and left the rig floor to seek help from another driller onsite.

In normal cleanout operation procedures, certain valves are closed prior to turning on the compressed air, which allows control over the flow of debris out of the hole and into a catch pond. Once the valves are prepared, the driller indicates to the derrickman that the area is ready for the compressed air. At some point between the senior driller preparing for cleanout and the derrickman leaving the floor to turn on the air compressor, there was a lack of communication and the air compressor was activated without the senior driller’s knowledge, prior to the prescribed valves being shut. After starting the air compressor, the derrickman returned to the rig floor and, as he walked to his next assignment, the rotary table erupted. The pressure normally used to complete the cleanout work is a minimum of 20 pounds per square inch. Within minutes, the kelly had pressurized well beyond this point to 150 pounds per square inch. The victim, who was still on the rig floor in close proximity to the kelly, was also unaware that the air compressor had been turned on. The compressed air, at full pressure with no valves closed to control or direct the flow, blew the kelly bushing, drillpipe slips, and debris out of the rotary table; all of which struck and landed on the victim.

Discussion: Employers should develop, implement, and enforce standard operating practices and procedures for all drilling operations to safeguard against unexpected energization or startup of equipment/machinery, or hazardous energy release during servicing and maintenance. These written practices and procedures should be reviewed at least annually. In this incident, standard operating procedures for performing cleanout, and training to those procedures, were needed to help monitor air and hydraulic pressure and control pumps and compressors. Had a standard written operating procedure been in place and complied with by the crew, this incident may have been prevented. While using compressed air is a normal cleanout practice, the area around the rotary table becomes highly hazardous during the procedure and requires certain precautions, such as following each step in order, knowing where debris will go before the air is started, and clearing crew members from dangerous areas. With enforced, documented procedures, the chances of inadvertent hazardous energy release are reduced.

Discussion: Employees should be trained thoroughly and formally on the standard operating procedures that are relevant to their duties and assignments. In addition, employers should consider thorough skill evaluations or screening for functional skills prior to hire or work assignment. For operations, such as performing cleanout on a drilling rig, the potential hazards of blowouts during the operation should be addressed, as well as ways to minimize or eliminate the hazards. In addition, training should emphasize the importance of establishing and maintaining good communication between all crew members while performing all work procedures. Documentation of the training should be kept on file with the company, and periodic retraining of employees should be done. Retraining should always occur when there are changes in the equipment, processes, or hazards present. Oil and gas industries should consider consulting sources such as publications from the International Association of Drilling Contractors (IADC; http://www.iadc.org/external icon) (Link Updated 4/1/2013) and OSHA’s Oil and Gas Well Drilling and Servicing eTool (https://www.osha.gov/SLTC/etools/oilandgas/ general_safety/general_safety.htmlexternal icon) for information on safety and training.

A Top Drive is an essential piece of drilling equipment; it is basically a large motor system which is hoisted in a derrick, mast or drilling rig. Top Drives can be used in a variety of rigs including truck-mounted rigs and offshore rigs.

Top Drive Systems have a plethora of benefits! Like we mentioned above, one of the most substantial benefits of this system is that they can be easily installed on any mast or derrick. Top Drive Systems also work as replacements for Rotary Officers and Kelly Systems – meaning there are fewer systems and parts to keep track of.

Top drives start the necessary rotation that is needed to move the drill stem. This means that a Kelly System and Kelly bushing are not required for Top Drive Systems; rather, a master bushing and a rotary table should be used for support. Mast bushings and rotary tables will support the weight of the slip and drill stem, and also serve as a conduit for the drill stem to be lowered or raised into a wellbore.

Because a Kelly System is not necessary, the length of each strand is longer than normal and makes up more than a single joint. When you drill with a Top Drive, you can expect the stand of the drill pipe to be composed of three drill pipe joints. This means that Top Drives can drill about 90 feet before making a connection, whereas with a Kelly System, you will make a connection at about 30 feet deep.

Another difference between a Kelly and a Top Drive is that a Top Drive System allows rotation and circulation while back reaming out of a hole. Kelly Systems do not have this capability and cannot rotate the drill stem.

Now that you understand what a Top Drive System is, how it differs from a Kelly System and what the benefits of Top Drives are, give us a call today to purchase one for your drilling site.

The main advantage of a rotary drilling hose vibrator hose is that it helps you move water from one point to another without much struggle. Hose pipes are also versatile and can be used for various activities in your home or at your workplace. Moreover, rubber horse pipes are durable since rubber is a strong material. This means that you won’t need to replace it often. Additionally, rubber hoses are less prone to cuts and abrasions. Another advantage of this hose pipe is that it absorbs shocks and vibrations. Also, there is no need for specialized bending or brazing since it can bend easily. Lastly, it reduces pressure surges and lubricates itself.

When buying a rotary drilling hose vibrator hose, there are several factors that you need to consider, including length, couplings, thickness, and price. The length of the rotary drilling hose vibrator hose is an important factor to consider. If you are taking the water to the furthest corner of your compound, consider getting a longer pipe for convenience. Also, if you are watering a large garden, a longer pipe will serve you better. Couplings or horse pipe fittings are also another important consideration. These are the accessories that help you connect your pipe to the water source. They can either be made from brass or plastic. Some people prefer plastic couplings since they are lightweight, but they can break easily. Brass fittings are heavier but long-lasting. Lastly, consider the thickness of the pipe. This refers to the number of layers used to make the rotary drilling hose vibrator hose. Thickness determines the weight of the pipe and ease of bending.
