旋冲钻井技术是一项新型的石油钻井工艺技术，是提高硬地层钻井效率的有效方法之一。实现旋冲钻井的工具就是冲击器。它不需增加任何动力设备，只在目前旋转钻井的基础上安装液动冲击器即可进行旋冲钻井。文中主要介绍了射流式冲击器的结构和工作原理，以及在四川地区的川孝164井和川峰188井应用情况。实践证明旋冲钻井比常规钻井硬地层机械钻速可提高40％以上。
Rotary drilling technology is a new type of oil drilling technology, which is an effective method to improve the drilling efficiency of hard formations. The implement for rotary drilling is the impactor. It does not need to add any power equipment, only the current rotary drilling based on the installation of hydraulic impactor can be rotary drilling. This paper mainly introduces the structure and working principle of jet impactor, as well as the application of Sichuan-Xiaoguan 164 and Chu-Feng 188 wells in Sichuan Province. Practice has proved that rotary drilling than conventional drilling hard formation penetration rate can be increased by 40% or more.
