kelly hose drilling definition price

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.

The main advantage of a kelly 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 kelly hose, there are several factors that you need to consider, including length, couplings, thickness, and price. The length of the kelly 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 kelly hose. Thickness determines the weight of the pipe and ease of bending.

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.

One or more valves installed at the wellhead to prevent the escape of pressure either in the annular space between the casing and the drill pipe or in open hole (for example, hole with no drill pipe) during drilling or completion operations. See annular blowout preventer and ram blowout preventer.†

API 7K Rotary Drilling hoses also called oilfield drilling hoses, vibrator hoses, mud hoses, cementing hoses, kelly hoses, de-coking hoses, for the steady high pressure oilfield service. PME Grade D and Grade E rotary hose are designed and produced for mud delivery and cement service on the drilling rigs, by pumping mud at extra high pressure in oilfield drilling operation and exploration.

PME Rubber High Pressure Rotary Drilling Hoses, API 7K Certification, Grade A, Grade B, Grade C, Grade D, Grade E, Grade F.The rotary connection between mud pump and standpipe is called mud hose or kelly hose.

Drilling rotary and vibrator hoses (High Pressure Drilling Hoses) are designed as API 7K Spec as the flexible connection between the standpipe and swivel for pumping mud at a very high pressure in oil drilling and exploration. This hose features high strength spiral steel wire reinforcement which provides a very flexible connection capable of withstanding high pumping pressures at API working pressures, also called mud hose, cement hose, kelly hose or shock-resistant hose.

Our high pressure drilling hoses are often equipped with API end fittings. Connection type covers LP, NPT, TBG and BSPT thread, welding or integral forged union or flange.

Kelly bars (also called grief joints, kelly joints and kelly stems) are used during the execution of boreholes by hydraulic rotary drilling rigs. The bars themselves are hollow and attach to the top of the drill column. Kelly bars operate by transferring the torque and crowd force from a rotary drive tool to the drilling tool. Many kelly bars can be applied to any type of piling rig that is available on the market.

Kelly bars can be divided into two main types: friction kelly bars and interlocking kelly bars. Friction kelly bars are named such due to the frictional contact created between the rails of each element. Interlocking kelly bars, on the other hand, do not have frictional contact between the rails of each element, but instead have drive ribs that are welded with lock devices in order to transfer the maximum amount of torque to each scope. Standard kelly bars are manufactured to be fully lockable systems with a mechanical locking mechanism between each element and the outer bar and rotary drive.

When purchasing a kelly bar for a drill rig, it"s important to look for bars made of high-quality steel with strong mechanical features. No matter whether buying kelly bars new or used, it"s also good to look for bars that include origin and quality certificates to guarantee their reliability and longevity. All kelly bars can be purchased with a damping noise system, which can help to reduce the disruptive, high-frequency noises produced during operation; a damping noise system comprises of a phono-absorbent material applied to the outer scope of the kelly bar, which is protected by a steel plates.

The rotary system on a drilling rig is the system that causes the drill bit rotate at the bottom of wellbore. We have discussed some components of the rotary system when we discussed rotary table and top-drive rigs, but we have not yet discussed the entire system.

A schematic of the rotary system is shown in Figure 9.07. As we can see in Figure 9.07, the rotary system shares many components with the circulation system. This is because in the rotary system, these components rotate in support of causing the bit to rotate, while in the circulation system, these components act as conduits for the drilling fluid.

The Bottom-Hole Assembly is comprised of any bottom hole equipment required to drill the current section of the well. A bottom-hole assembly may be as simple as a Drilling Collar. Drill collars are sections of heavy, thick walled pipe used to add weight-on-bit to the drill string. More complicated bottom-hole assemblies may include Jars, downhole directional steering and positioning equipment, logging-while-drilling, and measure-while-drilling equipment.

At the end of the drill string and bottom-hole assembly is the drill bit. There are many types of drill bits, but we will focus on two types of drilling bits, the Tri-Cone (or Roller Cone) Bit and Fixed-Cutter Bit. In addition, we will be discussing two variants of the tri-cone bit: the milled-tooth bit and the insert bit. All of these bits can be classified as in the following bullet list:

Tri-cone bits are the most common drilling bits and, historically, have been the workhorse of the drilling industry. As the name implies, tri-cone bits contain three cones, each of which contain cutting teeth.

One design feature of the tri-cone bit is the interaction of the teeth on the different cones helping to remove any small cuttings or sticky shales/clays (Gumbo Shales) that may get lodged between the teeth and reduce the efficiency of the bit. This phenomenon of cuttings and clays getting lodged between bit teeth is referred to as Bit Balling and results in slower Rates-of-Penetration (ROP) of the drilling process. The self-cleaning action of the teeth in a tri-cone bit is designed to reduce the bit balling.

Milled-tooth tri-cone bits are mainly used for drilling through soft rock formations. This is because, no matter how strong the steel used in the construction of the cone, hard rock can cause excessive wear and degradation of the teeth.

While the insert bit helps to alleviate the issues with tooth-wear, there is an additional source of wear that can shorten the life of a drilling bit. Due to the moving parts associated with a tri-cone (or roller) bit, the bit requires a bearing where the moving parts meet and move past one another. Thus, the wear on the bearings may also shorten the life of the bit.

The PDC bits are used to drill through very hard rock formations or for extended bit-life drilling. These bits have a large initial cost but because of the hard teeth and lack of any moving parts have a longer bit-life. One recent innovation for PDC bits in geologic basins with many shallow (short-footage) drill sites is the ability to rent the drill bit from the drilling company rather than to purchase it from a tool company. This innovation allows for an operating company to rent the bit and to use it for the footage that they require before relinquishing it to another operating company.

We have discussed that the tri-cone bits and the fixed cutter bits have different drilling actions. Here is a YouTube video, "Drill Bits - Oil and Gas Drilling: From Planning to Production" (3:26), that demonstrates the differences of the explosive, gouging, and crushing action of the tri-cone bit and the scraping action of the fixed cutter bits:

While we"re out of the hole the operator also wants to switch to a track hone bit. This style of bid is less aggressive than a PDC and will drill a little slower. Bit selection is very important part of drilling a well so let"s go review that now.

Tungsten carbide insert, or TCI bits, have tungsten carbide treated inserts that gouge, chip, and crush rock. Tungsten carbide is one of the hardest materials known and TCI bits are capable of drilling some of the hardest and most abrasive formations. Tungsten carbide inserts come in a variety of shapes and because of their appearance TCI bits are often called button bits.

Polycrystalline diamond compact, or PDC bits, have tungsten carbide cutters topped with hard caps of diamond composite material. The cutters are angled and arranged to shear channels in the rock. The diamond caps are made by heating and compressing artificial diamond grit with tungsten carbide and other metallic binders. PDC bits come in a variety of designs that can be used for an extensive range of drilling requirements. PDC bits are much more expensive than roller cone bits but can generally penetrate faster and last longer than roller cone bits which saves drilling costs.
