Product Introduction

Independently developed, designed, and manufactured by our company, this high-temperature, equal wall thickness, long-life screw drilling tool uses high-temperature hydrogenated nitrile rubber as the core material, combined with our proprietary high-temperature resistant formula. It operates normally at temperatures up to 240°C and is suitable for conditions such as saturated brine cement slurry and oil-based mud. It maintains stable performance in extreme environments, ensuring smooth operations.

Long service life, reducing drilling costs and significantly minimizing tripping frequency.

High build-up rate, achieving over 15°/30m.

High overall rotation speed with excellent stabilization performance.

Low-pressure consumption structure, reducing pump pressure by 1-2MPa.

Key Features

Premium high-strength alloy structural steel.

High-strength, long-life threaded connections.

All wear-resistant components made of diamond.

Supersonic flame-sprayed tungsten carbide rotor.

Equal wall thickness, imported oil-resistant, high-temperature hydrogenated nitrile rubber.

Precision linear control, high-efficiency, low-pressure consumption motor.
