What role does non-magnetic drill pipe play in drilling? -- Yikuang Technology
Function: Since all magnetic measuring instruments induce the geomagnetic field of the borehole when measuring the direction of the borehole, the measuring instrument must be a non-magnetic environment. However, in the drilling process, the drilling tool is often magnetic, has a magnetic field, affects the magnetic measurement instrument, can not get the correct well trajectory measurement information data, the use of non-magnetic drill collar can implement non-magnetic environment, and has the characteristics of the drill collar in drilling. Working principle: ① geomagnetic field line; ② magnetic measuring instrument; ③ steel drill collar; ④ interference magnetic field line; ⑤ bit joint; ⑥ non-magnetic drill collar interference magnetic field line above and below the non-magnetic drill collar has no effect on the measuring instrument part, so the non-magnetic drill collar is

Integral (integrated) pier rough drill pipe-Yiguang Technology
Integral (integrated) pier rough drill pipe, drill pipe joint and drill pipe body are integrated structure, no friction weld, divided into drill pipe inner and outer thickening process. By referring to the structure of the oil drill pipe, the original drill pipe joint and the drill pipe body are connected to the improved integral thickening structure by welding, which eliminates the problem that the performance of the original weld area is difficult to guarantee, and improves the overall performance of the drill pipe. In order to improve the overall strength of the drill pipe, the drill pipe is treated with overall tempering, and the joint is phosphated. The overall fatigue strength and shear strength were significantly improved.
