Drilling Rig Tools Non Magnetic Drill Collar For Oilfield

Product parameters

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 collar has special design requirements, so it will have unique corrosion resistance problems. The drill collar is the bottom of the drill string. Its weight will generate a force on the drill bit, which can be drilled out, and the stiffness of the drill collar can prevent force transmission. Traditional drill collars are made of alloy steel, and like other parts of the drill string, their corrosion usually does not cause any problems unless they are threaded. A typical drill collar is 30 feet long and 4 to 9 inches in diameter.

Advantages

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 carries a magnetic field, which affects the magnetic measuring instrument and cannot obtain the correct wellbore trajectory measurement data. Non-magnetic environment can be realized by using non-magnetic drill collar, which has the characteristics of drill collar during drilling.

Used in

Pipeline transportation, boiler pipes, hydraulic/automobile pipes, oil/gas drilling, food/beverage/dairy products, machinery, chemicals, mining, building decoration, special uses.
