摘　　要：带机械锁紧机构的液压式随钻震击器集液压式与机械式震击器功能于一体,采用液压原理与机械原理,取长补短达到优势互补,提高了工具的一次下井随钻时间和整机寿命。该复合震击器具有防误震、在钻柱中连接位置自由等特点,适用于定向井、大位移水平井、超深井以及欠平衡空气钻井作业等。介绍了机械液压式随钻震击器的结构、工作原理及性能特点。现场应用表明:在使用过程中避免了误震问题,可满足钻井工程的需要。The design, characteristics, development and oilfield application of a hydraulic/mechanical drilling jar are mainly describes. Hydraulic/mechanical drilling jar is a kind of new downhole tools, designed for directional wells, and extended reach horizontal wells, ultra-deep wells or complex wells. The jar is also appropriate for under-balanced air drilling. The jar was developed to overcome the usual shortcomings associated with purely hydraulic or mechanical jars, yet it retains the advantages of both concepts. So far, the serial hydraulic/mechanical drilling jars have been put into the industry application and field-proven design meets the requirement of modern drilling operatlons.
