What is a drill pipe?

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) Pipe Body + Tool Joint

What is a high strength drill pipe?

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.

What is a pipe body in a drilling machine?

①Pipe 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.

What are drill pipes & drill collars used for?

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.
