The blast furnace drill pipe is the basic component of the drill string. It is made of seamless steel pipe (the wall thickness is generally 9~11mm). Its main function is to transmit torque and transport drilling fluid. It continues to deepen, so it occupies an important position in oil drilling.
It is composed of seamless steel pipe, the wall thickness is generally 9~11mm, and it is composed of two parts: the drill pipe body and the drill pipe joint. There are two ways to connect the pipe body joint of the drill pipe: one is to connect with a thin wire buckle, that is, there are thin male buckles at both ends of the pipe body, which are connected with the female thin buckle at one end of the joint. The fine button drill pipe; the other is that the pipe body and the joint are butt welded together by friction welding, which is called the butt welding drill pipe
Drill pipes are regularly inspected for flaws, buckles repaired, and hardbands welded.
Check the wear of the hoop and body every time you drill down, and return to the factory for maintenance in time.
Add corrosion inhibitor and coating to drill pipe, and brush oil when not in use.
Use waste oil for maintenance.
If the flaw detection fails, it will be scrapped.
During the process of use, the blast furnace drill pipe must be able to withstand huge internal and external pressure, twisting, bending and vibration. In the process of drilling under pressure, the drill pipe can be used for many times. In the process of drilling under pressure, two kinds of moments act. On the drill pipe to realize the cutting of the pipe by the rotation of the sleeve cutter and the feed assembly to push the drill pipe to the pipe for depth displacement
In drilling construction, the drill pipe that is replaced each time should be carefully maintained, check whether the drill pipe thread is qualified, and the unqualified drill pipe cannot be inserted into the well to ensure the safety of the drilling construction process.
