| 发明名称 | Downhole motors with a lubricating unit for lubricating the stator and rotor | ||
| 摘要 | In aspects, the disclosure provides a drilling motor that includes a lubricating unit that selectively supplies a lubricant to the drilling fluid before the drilling fluid passes through the drilling motor so as to lubricate the stator and/or the rotor to reduce friction between the stator and the rotor and to reduce wear of the motor. | ||

| 主权项 | 1. An apparatus for use downhole, comprising: a stator having an inner contour surface; a rotor having an outer contour surface disposed in the stator, wherein the outer contour surface of the rotor comes in contact with the inner contour surface of the stator; and a lubricating unit configured to selectively discharge a lubricant from a reservoir source thereof into a fluid so that the lubricant lubricates one of the inner contour surface of the stator and outer contour surface of the rotor when the rotor rotates in the stator from the fluid flowing between the stator and rotor, wherein the reservoir source is disposed in one of the stator and the rotor. | ||
