A positive-displacement downhole motor uses drilling fluid as its power medium, converting the high-pressure fluid energy of the fluid into mechanical energy that drives the drill bit to rotate, thereby directly powering the drill bit for drilling operations. This motor is widely used in oilfield and coalmine operations—including drilling, deviation setting, directional change, core sampling, hole expansion, window drilling, and workover processes for directional wells, horizontal wells, cluster wells, and vertical wells—as well as in composite drilling applications.
Provides over 30 different specifications of PDM suitable for wellbores ranging from 1–7/8 "to 26" in diameter (outer diameter: Φ38～Φ305).
Available in various structural designs including straight, single-bend, double-bend, and adjustable-angle configurations.
Available heat resistance temperature ranges of ≤120℃, 120℃～150℃, 150℃～180℃, and 180℃～200℃.
Various specifications of PDM suitable for oil-based slurries and saturated salt cement slurries are available.
Various models of PDM with constant wall thickness are available.
Provide customers with customized services by developing and designing PDM tailored to their specific requirements.
Sliding drilling – where the drill string does not rotate – utilizes a curved casing to achieve inclination change, slope reduction, and directional deviation; this method is widely employed in directional wells, horizontal wells, and cluster wells.
High torque output from the bottom of the well drives the drill bit directly; under the composite drilling mode, the drilling speed is significantly increased.
During slide drilling, the drill pipe does not rotate, reducing the risks of drill pipe wear, fatigue, and joint break-out.
With decades of extensive experience in the manufacturing of oil and gas extraction equipment, the company boasts a robust quality control system, ensuring consistently reliable product quality.
Comprehensive specification range suitable for various wellbores; compatible with all well types and a wide range of drilling fluids.
Providing high-quality, fast service with 24/7 availability and prompt response – fast service.
