With the exploration and development of deep and ultra-deep wells, the performance requirements of drilling motor (or downhole motor,mud motor , positive displacement motor) tools are getting higher and higher. The working environment temperature in the well is often higher than 200℃. The motor stator of conventional drilling motor tools is composed of a stator shell and a rubber bushing, and is temperature resistant. The level can only reach about 120℃, and its high temperature resistance is far from meeting the needs of normal drilling. The all-metal motor is not sensitive to temperature changes and can work in an environment of about 300°C. Therefore, the all-metal motor drilling motor tool is more suitable for drilling in high-temperature wells.

The all metal drilling motor tools developed by the company are made of metal parts. The all-metal motor stator is more wear-resistant and corrosion-resistant. The output power, high temperature resistance and aging resistance of the motor are significantly better than those of conventional drilling tools. Improve, thereby prolonging the service life of drilling motor tools.
