108mm Spiral Non Magnetic Drill Collars For Oilfield Equipment

108mm Spiral Non Magnetic Drill Collars For Oilfield Equipment

Drill Rig Tools Non Magnetic Sprial Drill Collar For Oil Field Equipment

Features

It has good low permeability and high strength. Excellent mechanical properties, excellent resistance to intergranular corrosion, crack resistance and wear resistance.

Advantages

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

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 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. 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.

Used in

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