Product Description

Heavy Weight Oil Well API Non Magnetic Drill Collars

API Non Magnetic Drill Collar ( NMDC ) For Oil And Gas Drilling


The non-magnetic drill collar is made of low carbon high chromium manganese alloy steel. It is refined by strict chemical composition, and its mechanical properties are obtained through forging. When the magnetic field strength is 1×105/4marea/m, the relative permeability bias of non-magnetic drill collars is r≤1.010. The magnetic induction intensity gradient of non-magnetic drill collar at any interval of 100mm along the inner hole≤0.05


Since all magnetic measuring instruments sense the borehole's geomagnetic field when measuring the direction of the borehole, the measuring instrument must be in a non-magnetic environment. However, in the drilling process, the drilling tool is often magnetic and has a magnetic field, which affects the magnetic measuring instrument and cannot obtain the correct wellbore trajectory measurement information data. The use of a non-magnetic drill collar can implement a non-magnetic environment and has the characteristics of a drill collar during drilling .
