Oil drill pipe is a component in a tool that connects the drill bit and transmits power. The typical components of a drill string include: drill bit, drill collar, drill pipe, stabilizer, specialized joint, and square drill rod.In oilfield drilling engineering, petroleum drill rods are the main components connecting the ground rotation system, lifting system, circulation system, drill collars, and drill bits. Through them, the rotary table drives the drill bit to rotate, the hook drives the drill bit to rise and fall, and the mud is sent to the bottom of the well to form a circulation, thereby achieving the breaking of rock layers by the drill bit and continuous drilling.

Its main function is to: (1) lift the drill bit; (2) Apply drilling pressure; (3) Transfer power; (4) Transporting drilling fluid; (5) Perform special tasks such as squeezing cement, handling underground accidents, etc.
