普光气田防斜打快技术研究与应用

井斜问题是油气井生产中一个非常突出的难题，尤其是在高陡构造的深井钻井中，如何实现防斜打快一直是钻井界努力探索的课题。为此，介绍了普光气田防斜打快技术研究取得的新进展。实践表明，复合钻井、垂直钻井、空气钻井、空气冲击钻井在普光气田实现了防斜打快的预期目标，成为了加快普光气田勘探开发进程的重要技术。分析认为，垂直钻井技术、空气钻井技术和空气冲击钻井技术将会成为国内深井、特别是高陡构造深井、超深井防斜打快的核心技术之一。

Research and Application of Anti-deflection & Fast Drilling Technology in Puguang Gasfield

Well deflection is a prominent problem encountered in oil and gas well drilling, especially when drilling in deep high dip formations. To drill fast and with much less or without deflection is always the goal which the drilling industry has sought for. Herein the new advancements achieved in fast anti deflection drilling in Puguang Gasfield have been introduced. The practice proves the composite drilling, vertical drilling, air drilling, and air percussion drilling contribute to the expected fast anti deflection drilling, are the important technologies to quicken the exploration and development in Puguang Gasfield. By comparison, it is recognized the vertical drilling, air drilling and air percussion drilling will soon become the core technology of anti deflection &; fast drilling in domestic deep wells, particularly in steep structures.
