Description

China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of drill pipe in China, featured by competitive price and fast delivery. Welcome to buy high quality drill pipe in stock here from our factory.

Drill pipe is a hollow, thick-walled piping that transmits drilling fluid and torque through the wellbore to the drill bit on a drilling rig, which is manufactured to withstand severe internal and external pressure, distortion, bending, and vibration as it both rotates and lifts the bottom hole assembly (BHA)

Structure

Pipe Body + Tool Joint

① Pipe Body It is a long cylindrical steel pipe that transmits the rotary motion of the drilling machine to the drill bit and at the same time withstands the tensile force and pressure during drilling. The tube body is usually made of high-strength alloy steel to ensure its durability and performance under extreme conditions.

② Tool Joint Drilling pipe is threaded on each end in a section of pipe referred to as the tool joint, which enables the connection between drill rods and between drill rods and other drilling tools such as drill bits or drill collars.

Why choose Vigor as your drill pipe supplier?

① Vigor supplies different grades of API 5DP Drill Pipe, more details are as following chart.

API Drill Pipe Grade	Minimum Yield Strength (psi)	Minimum Tensile Strength (psi)
E-75	75,000	100,000
X-95	95,000	105,000
G-105	105,000	115,000
S-135	135,000	145,000

●Grade E is used in medium-depth wells ranging from 10,000 to 15,000 feet. exhibits the lowest yield strength per unit area with a yield strength of less than 80,000 psi. It is able to withstand a greater percentage of stretch or "strain" prior to fracture than higher-strength drill pipe grades. It is also more resistant to corrosion and cracking.

●Grades X-95, G-105, and S-135 are considered to be of high strength grades. They exhibit an increase in yield strength which normally used for the deeper wells.

③ Vigor's drilling pipe is manufactured, sampled, tested, and inspected following standard specifications such as the American Petroleum Institute (API).

Internal Upset: IU, EU, IEU

To enhance the joint strength, the butt welding parts at both ends of the pipe body are thickened. Internal Upset refers to a phenomenon in which the inner diameter at both ends of the pipe body is reduced, increasing the thickness of the pipe wall. Its outer diameter of the joint remains consistent and the joint's outer diameter is not excessively large. During rotation in the well, the joint has less contact with the wall of the wall and is also less worn.

IU: refers to a joint that comprises only a thickened internal pipe wall. This design enhances the connection strength while maintaining consistency in the outer diameter.

EU: In contrast to IU, the EU refers to a joint in which the outer tube wall is only thickened. This design offers additional protection and strength on the outside but may increase the overall outer diameter of the drilling pipe.

IEU: This design combines the characteristics of IU and EU, that is, the internal and external pipe walls of the joint are thickened. The IEU provides the highest strength and durability for drilling environments that withstand extremely high loads.

Application

Oil and Gas Drilling:

Drill pipes and drill collars are extensively used in oil and gas drilling operations. Drill pipes are used to transmit drilling fluid to the drill bit and provide the conduit through which cuttings are brought to the surface. Drill collars, on the other hand, are heavy, thick-walled tubular pieces that provide weight to the drill bit, helping to maintain directional control and stability during drilling.

Directional Drilling:

In directional drilling, where wells are drilled at angles or curves to reach specific targets, drill collars play a crucial role. By placing them near the drill bit, they help guide and control the trajectory of the wellbore.

Deepwater Drilling:

In deepwater drilling, where wells are drilled in offshore environments with significant water depths, drill pipes and drill collars are used to reach and explore hydrocarbon reservoirs beneath the seabed.

Geothermal Drilling:

Drill pipes and drill collars are used in geothermal drilling to access heat from within the Earth. Geothermal wells are drilled to tap into underground sources of steam and hot water for electricity generation and heating applications.

Mining Exploration:

In the mining industry, drill pipes and drill collars are used in mineral exploration. They are utilized to bore holes into the earth's crust to collect samples of rock and soil, helping geologists determine the presence of valuable minerals.

Water Well Drilling:

Similar to mining exploration, drill pipes and drill collars are used in water well drilling to access groundwater resources for domestic, agricultural, and industrial purposes.

Scientific Research:

Drill pipes and drill collars have been used in scientific research projects, such as ice core drilling in polar regions. These projects aim to extract samples from deep ice layers to study the Earth's climate history.

Environmental Monitoring:

In environmental studies, drill pipes and drill collars can be used to collect soil and sediment samples from various depths for pollution analysis and environmental assessment.
