Spiral Non Magnetic Drill Collars
Non Magnetic Drill Collar Spiral Drill Collars For Oil Field Equipment
Introduction
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 the non-magnetic drill collar
r≤1.010. Magnetic induction intensity gradient of non-magnetic
drill collar at random intervals of 100mm along the inner hole
≤0.05
Non-magnetic drill collars have unusual design requirements, thus
creating unique corrosion resistance issues. The drill collar is
the bottom part of the drill string. Its weight generates a force
on the drill bit, which enables the drill bit to be drilled out,
and the rigidity of the drill collar prevents the transmission of
force from buckling.
Features
It has good low permeability and high strength. Excellent
mechanical properties, excellent intergranular corrosion
resistance, crack resistance and wear resistance.
