摘　　要：空气锤钻井技术用于直井钻井可以提高机械钻速和防斜纠斜,同时也可用于定向井和水平井中,以提高机械钻速和缩短钻探周期。为此,介绍了国外空气锤钻井技术在定向井中的应用,包括自回转式空气锤钻井技术和空气螺杆马达驱动式空气锤定向钻井技术,分析其在油田的应用效果,以期对国内空气锤定向钻井技术提供技术参考。The application of air hammer drilling technology to vertical well drilling can improve penetration rate and deviation control. Meanwhile, it can be used in directional wells and horizontal wells so as to improve penetration rate and shorten the drilling cycle. Therefore, the application of air hammer drilling technology in directional wells abroad was introduced, including rotary air hammer drilling technology, air screw motor drive air hammer directional drilling technology and the effect of their application in oilfields. It is hoped that this technology can get widely known in domestic oilfields.
