API 5DP drill pipe is a kind of steel pipe with screw thread in the pipe end. It is used for connecting ground rig equipment and drill grinding equipment at the bottom of drilling wells. The main purpose of drill pipes is to transport drilling mud to the drill bit. It rises up, lowers and rotates together with the drill bit. Its strength must withstand the pressure, torque, vibration and other forces caused by the drill hole. In the oil and gas exploration and refining process, API 5DP drill pipe can be used for multiple times. ZS provides a number of drill pipes available in various sizes and weights to meet the drilling needs of co***nies in the oil and gas industry.
Functions of Drill Pipe
API 5DP drill pipe is mainly applied in oil and gas exploration and development, such as in the construction of deep wells, horizontal wells and large-displacement wells. Its main functions are as follows:
Drill pipes deliver torque and drive the drill bit to drill wells.
Exert pressure that can break the rock at the bottom of well on the drill bit.
API 5DP drill pipe transmits flushing fluid. Through the ground high-pressure slush pump or mud pump, drill mud enters into the inner hole of drill string, flows into the bottom of well to wash rock debris and to cool down the drill bit, passes through the annular ***ce between the drill string outer surface and well wall (carrying rock debris), returns to the ground.
Drill Collars are one of the parts of a drill’s string. Drill for the Collars is meant to provide weight for drilling purposes. The Drill Collars are thick walled tube like pieces that are machined from solid steel bars, although they are often made from plain carbon steel or the non magnetic alloy of copper and steel or other premium alloys that are non magnetic in nature. Drill collar has bars of solid steel that are drilled from one end to the other to provide a passage for pumping the drilling fluids through the collar.
Collars that are available for drilling have an external diameter that is made o |
