摘要
S8 8井在下奥陶纪的鹰山组地层钻遇 5 .7m的大溶洞 ,钻井液有进无出 ,多次堵漏无效 ,且负压钻进也不能建立正常的循环 ,最终实施强行钻进工艺 ,完成了四开钻井任务。介绍了该井强行钻进工艺设计及实施情况。
A 5 7m cavity was encountered when drilling Yingshan formation of lower Ordovician period in S88 well. Meanwhile, drilling fluid leak happened. The fourth drilling was achieved by forced drilling technology ultimately on condition that normal drilling fluid circulation couldn't be established by means of plugging and negative pressure drilling. The forced drilling technology design and practice is presented in this paper.
