摘　　要：在普光气田开发过程中,由于地层岩石致密、硬度高,地层倾角大、构造高陡,致使常规钻井技术施工时,钻进速度低,井身质量控制困难。气体钻井技术在该区的广泛应用大大提高了钻进速度,缩短了钻井周期,尤其是空气锤钻进工艺的应用,在极大提高钻进速度的同时克服了井斜难以控制等难题,大大加快了气田开发速度。文章就空气锤钻井工艺的碎岩及防斜机理进行了详细探讨,并结合其在PE-1、PE-3井的应用效果进行了分析总结。Because of stratigraphic rock mass, high rock rigidity, big inclination and steep conformation, the drilling speed is low and it is difficult to control the quality of the well during the conventional drilling construction. In this paper, it introduces the application of air hammer technology in the Puguang oil field. Firstly it describes the mechanism of rock crush and wellpath control, and then discusses the effect of air hammer applied in well PE -1 and PE-3.
