Common components of drilling teams are twist drills, drill strings, drill pipes, thrusters, unique connectors and square drill pipes.
The basic functions of the drill pipe are:
(1) Trigger the drill bit;
(2) Apply WOB;
(3) Transmission of power;
(4) Transport drilling fluid;
(5) Carry out special operations: squeeze cement, deal with underground accidents, etc.
Application of geological drill pipe for coal mine:
Drill pipe refers to a seamless steel pipe with an external thread at the end of the twist drill, which is used to connect the surface equipment of the drilling rig and the drilling rig equipment or bottom hole equipment located at the bottom end of the twist drill. The main purpose of the perforated pipe is to transfer the drilling fluid to the drill bit and to lift, reduce or rotate the bottom hole equipment together with the drill bit. Drill pipe must be able to withstand the world's largest internal and external pressure, twisting, bending and vibration. In the whole process of oil and gas extraction and extraction, the drill pipe can be used several times.
The light pipe and the original seamless steel pipe are made into drill pipe after several times of production and processing. Care is first treated with the steel pipe thickening process, the surface of the pipe is bent inward, and the wall of the steel pipe is thickened. One step of thermal insulation and broken bridge aluminum profiles, do a good job in thread processing, and plated with copper that can improve the degree of. A non-destructive quality management experiment was then carried out and the regulations for butt welds in seamless steel pipe bodies were followed. The tube body has to undergo welding heat treatment and welding to remove the residual working pressure. Avoid testing seamless steel pipe products prior to paint and packaging, including hardness testing, stability testing, and non-destructive testing.
