Non-Magnetic Drill Collar for Oil-Field

Oil-Field Non-Magnetic Drill Collar

Summary

• The Non-magnetic drill collars are made from non-magnetic steel bars with low-strength by combining a proprietary chemical analysis and a rotary hammer forging process with low magnetic permeability excellent machine ability, it will not interfere with the specialized directional equipment and will enhance the performance of the drilling operation.
• Non-magnetic drill collars function as housing for the MWD tools, while at the same time provide the weight for drillstring. The non-magnetic drill collars are suitable for all types of drilling including straight and directional applications.
• Each drill collar is fully inspected by internal inspection dept. All data obtained are recorded on the inspection certificate furnished with each drill collar. API monogram, serial number, O.D, I.D type and size of connections are stamped on recessed mill flats.
• We can provide three type of non magnetic drill collar according to the customer's order, include slick, spiral, and flex non-mag drill collar.

Slick Non-Mag. Drill Collar

• The slick non-magnetic drill collar provide the required weight on bit, and will not interfere with the directional drilling ability.

Spiral Non-Mag. Drill Collar

• The spiral non-magnetic drill collar is designed to allow greater flow area for drilling fluids, while providing the benefits of non-mag steel for complex drilling programs.

Flex Non-Mag. Drill Collar

• The flex non-magnetic drill collar is thinner and more flexible than standard drill collar. Their ability to make short radius turns, bend for high build angles, and pass through severe doglegs makes them ideal for use in directional and horizontal applications. Manufactured with non-magnetic steel, this drill collar is well suited for housing MWD equipment.
