More Information
Summary:The invention provides a self-excitation type hydraulic oscillation impactor which comprises a shell, and a cavity extending in the axial direction is formed in the shell so that fluid can penetrate through the cavity; the inner wall of the shell protrudes in the radial direction to form the vortex generating blocks; the central modulation tube is supported by the shell and accommodated in the cavity, and comprises a modulation tube main body and a modulation cavity which is limited in the modulation tube main body and axially extends; wherein the vortex generating block and the central modulation pipe are sequentially arranged in the flowing direction of fluid in the cavity. According to the self-excitation type hydraulic oscillation impactor, the hydraulic pulse frequency is effectively reduced through the hydraulic pulse jet flow modulation mechanism, and meanwhile the utilization rate of downhole hydraulic energy and the drilling efficiency are improved. 本发明提供一种自激式水力振荡冲击器，包含壳体，该壳体内部设置有轴向延伸的空腔以允许流体穿过；涡流发生块
