Application Scenarios:
This motor is primarily applied in oil and gas drilling projects where oil-based or synthetic-based mud is used for wellbore stabilization and drilling optimization. It is widely utilized in directional drilling, horizontal drilling, and deep/ultra-deep well drilling operations in complex formations such as shale, salt rock, gypsum, and water-sensitive formations—where oil-based mud is essential to prevent formation collapse and wellbore instability. Additionally, it is suitable for unconventional resource development projects (e.g., shale gas, tight oil) and offshore drilling operations that require high drilling efficiency and wellbore quality. The motor also performs reliably in high-temperature and high-pressure (HTHP) drilling scenarios with oil-based mud circulation, providing consistent power support for trajectory control and rock-breaking operations.
Product Advantages:
Firstly, it exhibits excellent oil resistance, with stator rubber materials (e.g., hydrogenated nitrile rubber, fluororubber) that can resist swelling, softening, and aging in oil-based mud, maintaining stable geometric shape and sealing performance for long-term operation. Secondly, the motor features enhanced wear resistance and corrosion resistance, with rotor surfaces treated with hard coatings (e.g., chrome plating, ceramic coating) to withstand abrasion and chemical erosion from oil-based mud, extending the service life of core components. Thirdly, it ensures stable power output and high hydraulic efficiency in oil-based mud environments, avoiding performance degradation caused by fluid viscosity changes, thus guaranteeing high drilling penetration rate and trajectory control accuracy. Moreover, the optimized sealing system prevents oil-based mud from infiltrating internal components, reducing wear of bearings and transmission parts and improving overall operational reliability. Finally, it maintains good compatibility with oil-based mud drilling systems, facilitating seamless matching with measurement-while-drilling (MWD) tools and various drill bits, simplifying on-site operation and maintenance, and lowering drilling costs in complex formation projects.
