Resumen de: US2025116159A1

The disclosure is in the technical field of oil drilling, and in particular relates to a directional well hydraulic clutch drill string full rotation controller, including a rotary assembly, a power assembly and a control assembly. It has two working states: compound drilling and directional drilling. According to the change of the tool face, adjusting the rotation speed of the upper drill string or the displacement of drilling fluid may change the working state of the controller and complete the directional drilling work. The directional well hydraulic clutch drill string full rotation controller has a low cost and high safety and reliability. When oriented, the drill string keeps rotating, which greatly reduces the friction of the drill string system, reduces the stick-slip vibration phenomenon of the drill bit, and thus increases the ROP. The research and development of this technology is of great significance to the petroleum industry.
