摘　　要：冲击回转钻进是一种高效、优质的钻探工艺,冲击器的好坏直接决定着冲击回转钻进的效果。在分析传统液动、风动冲击器使用过程中存在的不足的基础上,介绍了一种新型电动冲击器的设计思路、结构、工作原理及其技术优点。该新型电动冲击器用可充电电池组供电,通过开、关地表钻井泵来调节冲击器的冲击频率和冲击功。研究表明,该电动冲击器设计方案科学合理,技术优点显著,应用前景广泛。Percussive-rotary drilling is a drilling technology with high efficiency and quality, and its drilling efficiency mainly depends on impactor. After analyzing deficiencies of traditional hydraulic and pneumatic impactors, this paper introduced the design, structure, working principles and merits of a new electric percussive-rotary drilling tool. The new electric irnpactor is powered by rechargeable battery. Blow frequency and impact energy were adjusted by turning on and off the mud pump. Study shows that the design of electric impactor is scientific and reasonable and has obvious advantages. The electric impactor has a broad application prospects.
