Downhole motor of equal wall thickness for oil drilling equipment for deep-well operations
Equal wall thickness PDM is a new type of power drilling tool which is different from the conventional PDM.
- Advantages
- High torque: Compared with conventional PDM, it can output more torque, providing stronger power for drilling operations, and can effectively cope with complex drilling conditions such as deep wells and hard strata.
- Long service life: The service life of conventional PDMs is generally 150-200 hours, while the rubber bushings of equal wall thickness PDM do not suffer from rubber aging or rubber loss during the vulcanization process, and have a service life of more than 300 hours.
- High-temperature resistance: The structure design of equal wall thickness makes the heat dissipation of the tubing body more uniform, and the rubber bushing can be heated uniformly to avoid thermal lag phenomenon, which makes its performance more stable under high-temperature environments, and it can be adapted to the high-temperature working conditions of deep wells and wells with large displacements.
- Increase drilling speed: This kind of PDM increases the average mechanical drilling speed by 20% compared with the conventional PDM, which can effectively reduce the drilling cycle and save drilling cost.
- High safety: it can effectively reduce the occurrence of complicated downhole accidents and provide equipment guarantee for the risk-free drilling process.
produced are always of the best quality.
