       Non magnetic drill collars, also known as non-magnetic drill collars, are a type of non-magnetic drill collar made of austenitic stainless steel or K-Monel alloy. Because it lacks magnetism, it will not affect the direction of the compass. Non magnetic drill collars are often used because they not only have extremely low magnetic permeability, but also have good mechanical properties and corrosion resistance, providing a measurement environment for logging instruments that is not affected by the magnetic field of the drill string. During directional drilling, in order to use a compass inclinometer inside the drilling tool, a certain length of non-magnetic drill collar is connected to the lower part of the drill string, which depends on the inclination angle, azimuth angle, and geographical location of the drilling.
       The interference magnetic field lines above and below the non-magnetic drill collar have no effect on the measuring instrument, so the non-magnetic drill collar creates a non-magnetic environment for the magnetic measuring instrument, ensuring that the data measured by the magnetic measuring instrument is true geomagnetic field information.
