摘要
矿 2井是四川地区在推覆体构造上钻探的第一口定向井。实钻中 ,该井 31 1 .2井段井漏严重 ,卡钻频繁 ,钻至井深 1 5 2 2m(侧钻前 ) ,处理井漏和卡钻井下复杂损失时间 1 6 6 9h。为了从根本上解决该井的井漏及卡钻问题 ,侧钻后从井深 1 5 35 .2 7m使用充气流体钻进至井深 1 90 1 .0 0m下入 2 4 4 .5套管 ,钻井进尺 36 5 .73m 。
Well Kuang 2 is first horizontal well in Sichuan nappe structure.In practical drilling,Serious lost circulation and frequent sticking exist in 311.2 wellbore.When drilling to 1522m (before sidetracking),the time of treatment lost circulation and sticking is high up to 1669h.In order to solve the problems on lost circulation and sticking,using aerated fluid drill from 1535.27m to 1901 m after sidetracking and run in 244.5 casing,the downhole complex cases are effectively solved.
