摘要
在新疆油田夏72预探井三开欠平衡钻井施工中,首次使用了套管阀(DDV),通过配套技术,实现了欠 平衡钻进、起下钻、测井的多项欠平衡施工作业。在夏72三开所钻岩性较为复杂的情况下,裸眼段长度达到了 1511 m,创全国单井欠平衡进尺最高记录。
During underbalanced drilling in 215. 9mm hole of Xia 72 preliminary prospecting well in Xinjiang oilfield, firstly used the casing valve (DDV). Through applying matching technology, the underbalanced drilling, underbalanced tripping and underbalanced logging technologies were successfully used in underbalanced operation. Drilled rock property was very complex in 215.9mm hole of well Xia72, but the length of open hole section has 1511m, its underbalanced drilled footage is the longest in individual well in Chi-
