Significant advantages of non-magnetic drill collars
release time：2024-04-07

Non magnetic drill collars are a special type of drill collar made of low-carbon, high chromium manganese alloy steel refined through strict chemical composition ratios. This type of drill collar has good low magnetic permeability and high mechanical strength, as well as excellent intergranular corrosion cracking resistance and wear resistance.
Non magnetic drill collars are mainly used for monitoring during oil drilling, and their structure is the same as that of integral drill collars. In the process of oil and gas drilling, drill collars are the main tool, and the special properties of non-magnetic drill collars ensure that the measuring instrument is in a non-magnetic environment when measuring the direction of the wellbore, thereby avoiding interference from other magnetic field lines on the measuring device and ensuring that the data measured by the magnetometer is true information of the Earth's magnetic field.
Overall, non-magnetic drill collars are an important tool widely used in the field of oil drilling, and their unique non-magnetic and high-strength characteristics give them significant advantages in measuring wellbore direction.
