摘　　要：冲旋钻井技术是一种新型、高效钻进硬地层的方法。本文论述了冲击旋转钻井技术在石油钻探中应用的技术优势,探讨了冲击旋转钻井工具的发展现状及存在的问题。阐述了影响冲击旋转钻井技术发展的主要因素,提出了气动冲击器用于物探钻井开发方面存在的问题和研究方向。The revolving-drilling technique is one of the new-type and effective methods for hard rock drilling. The superi-ority of this technique in oil drilling industry is illustrated in this paper, and the developed status of rotary-drilling tools and the existed issues ware discussed. This paper presented some main factors affecting the development of revolving-drilling technique. Finally, the paper presented the problems existed in the aspect of using air hammer for geophysical drilling and the direction of studied direction.
