Product Description

Non Magnetic Oil Rig Drilling Spiral Drill Collar

Spiral Drill Collar Non Magnetic Drill Collar For Oil Rig Drilling


Since all magnetic measuring instruments can sense the geomagnetic field in the borehole when measuring the borehole direction, the measuring instruments 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 can not get the correct wellbore trajectory measurement information data. Non-magnetic environment can be realized by using non-magnetic drill collar, which has the characteristics of drill collar during drilling.


It has good low permeability and high strength. Mechanical properties, excellent intergranular corrosion cracking resistance and excellent wear resistance.
