What role does non-magnetic drill pipe play in drilling? -- Yikuang Technology
Release time:
2022-01-07
Author:
Source:
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

The instrument must be a non-magnetic environment. However, in the drilling process, drilling tools are often magnetic, with a magnetic field, affecting the magnetic
The measurement instrument can not obtain the correct borehole trajectory measurement information data, the use of non-magnetic drill collars can implement a non-magnetic environment, and has.
Characteristics of drill collars 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
The interference magnetic field lines above and below the non-magnetic drill collar have no effect on the measuring instrument site, so the non-magnetic drill collar is a magnetic measuring instrument.
A non-magnetic environment is created to ensure that the data measured by the magnetic measuring instrument is true geomagnetic field information.
