Non-magnetic drill collar is a tool specifically designed for use in the oil drilling process. Its primary function is to create a non-magnetic environment to ensure that the magnetic measuring instrument can accurately measure the direction and trajectory of the hole. Non-magnetic drill collars are made of low carbon high chromium manganese alloy steel, which has good low permeability and high strength mechanical properties after a strict chemical composition ratio and refining process.
Manufacturing materials and characteristics
Non-magnetic drill collars are typically manufactured from N1310 low-carbon alloy steel, which is subjected to a rigorous chemical composition analysis and forging process to ensure that its hardness, toughness, impact value and corrosion resistance meet standards, with good low permeability and machinability . In addition, non-magnetic drill collars also have good intergranular corrosion cracking resistance and wear resistance 1.
Working principles and application scenarios
In the process of oil drilling, all magnetic measuring instruments sense the geomagnetic field in the hole when measuring the direction of the hole. Because the drill tool is usually magnetic, it will affect the accuracy of the magnetic measuring instrument. Non-magnetic drill collars create a non-magnetic environment to ensure that the magnetic measuring instrument can measure the true geomagnetic field information, so that the correct borehole trajectory measurement data 5.
