Patent number: 7426965Abstract: The invention discloses a fluid-driven impactor, a power transmission mechanism for the impactor and the use of the impactor. In the prior art, the working life of the impactor is short, since a rubber primary seal and an upper fluid-diverging lid for the fluid-driven impactor are both liable to erosion and the efficiency in transmitting power is low due to the complexity of the power transmission mechanism. In order to increase the drilling speed and/or extend the life of the impactor, the side cavity passage is formed in such a way that the inner wall of the outer pipe is isolated from the side cavity passage in a watertight manner without the use of the rubber primary seal. The loss in transmitting power is minimized by integrating the anvil of the power transmission mechanism and the lower joint.Type: GrantFiled: January 14, 2003Date of Patent: September 23, 2008Assignees: China Petroleum & Chemical Corporation, Exploration & Production Research Institute, SinopecInventors: Xinghua Tao, Guoqiang Xu, Xutian Hou, Yijin Zeng
