127mm 5" Non Magnetic Drill Collars For Directional Drilling
Non Magnetic Collar Sprial Drill Collar For Oil Field
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 by forging.
When the magnetic field strength was 1× 105/4marea/m, the relative
permeability bias r of the non-magnetic drill collar ≤1.010. The
magnetic induction intensity gradient of the non-magnetic drill
collar at an arbitrary interval of 100mm along the inner hole is
≤0.05
Non-magnetic drill collars have unusual design requirements,
resulting in unique corrosion resistance problems. The drill collar
is the bottom part of the drill string. Its weight generates the
force on the bit so that the bit can be drilled out, while the
stiffness of the drill collar prevents the transfer of force from
buckling. Conventional drill collars are made of alloy steel and,
like the rest of the drill string, their corrosion usually does not
cause any problems, except for their threaded connections. A
typical drill collar is 30 feet long and 4 to 9 inches in diameter.
Features
It has good low permeability and high strength. Excellent
mechanical properties, excellent intercrystalline corrosion
resistance, cracking resistance and wear resistance.
Advantages
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 .
