摘　　要：介绍了冲旋钻进技术的应用概况,阐述了国内外冲旋钻进用冲旋钻头的技术现状,包括改装牙轮钻头、冲击类专用钻头(硬质合金钻头、金刚石钻头)、新型钻头等,并分析了它们各自的特点,提出了冲旋钻头的发展趋势。对我国冲旋钻头的结构优化和新型冲旋钻头的研制具有指导作用。The application actuality of the percussion-rotary drilling is introduced, and the current situation at home and abroad of the percussion-rotary bit, including developed cone bit, special bit （carbide cobalt, diamond bit）, novel bit, etc, is also described. Their features was analyzed, the development trend of the percussion-rotary bit was raised. Therefore, it is of great guidance both to the structure optimization design of percussion-rotary bit and to the research of novel bit.
