Drill pipe in reverse circulation drilling machine

The drill pipe of the gas lift circulating drill has the following functions:
Transfer torque: The drill pipe transmits torque to the drill bit by connecting the drill bit and the rotating device of the rig, so that it can rotate and drill.
Supporting drilling fluid pipe: The drill pipe is a part of the drilling fluid pipe to support and fix the drilling fluid pipe to ensure the smooth flow of drilling fluid.

Transfer drilling force and weight: The drill pipe connects the drill bit and the rig to transfer the drilling force and weight to the drill bit, so that it can successfully drill.

Transmission of drilling signals: Measuring instruments are usually installed on the drill pipe, which can transmit relevant parameters and signals during drilling, such as drilling speed, bit weight, drilling direction, etc., to provide reference and monitoring for drilling operations.

In short, the drill pipe plays a number of important roles in the gas lift circulating drill, such as connection, force transmission and signal, and is an indispensable part of the drilling operation.
