摘　　要：对YZX130型液动锤的结构和工作原理进行了介绍,通过室内调试和测试总结出其主要特点。在WFSD-4孔中的应用证实,YZX130型液动锤可大幅度提高机械效率和回次进尺,尤其在坚硬破碎地层效果更佳,而在塑性较高的软弱松散地层效果则相对较差。This article introduces the structure and working principle of YZX130 hydraulic hammer,and summarizes its main features by analyzing the debugging and testing results. The application of YZX130 hydraulic hammer in WFSD-4well proved that this hammer could substantially increase round trip coring length and rate of penetration,especially in hard and broken formation. However,its effect in weak and loose formation with high plasticity was relatively poor.
