摘要
通过塔河油田沙114、沙115、沙116等这些重点井的钻探,针对盐膏层的复杂情况,形成了一系列超深井巨厚盐膏层钻井技术,主要包括钻开盐膏层前承压堵漏技术、岩膏层安全钻进技术、扩孔技术、钻井液技术等,实现了超深井巨厚盐膏层的安全顺利钻进。
Aimed at the complicated feature of extremely thick salt-gypsum bed in exploration wells of Shal4,Shall5 and Shall6 of Tahe oilfield,some drilling technologies are developeded.These technologies include loading seal before drilling and safety drilling in,reaming,drilling fluid and cementing,by which can smoothly realize drillling in the extremely thick salt-gypsum bed in super-deep hole.
