摘要
焦石坝地区地质条件复杂,存在水层与气层,上部地层钻遇裂缝、溶洞,发生恶性漏失堵漏施工困难的等情况较普遍。如焦页8-2HF井、焦页5-2HF井等井在钻井施工过程中,均钻遇溶洞裂缝。针对这种情况,对该地区的钻井难点进行分析,提出了解决焦石坝地区钻井技术难点的具体对策。
Geological conditions of Jiaoshiba are complex, so there are many problems in drilling. For example, drilling operation of Jiaoye 8-2 HF and Jiaoye 5-2HF encountered cracks and caves. Aimed at above problems, drilling challenges were analyzed; detailed measures to solve these challenges were put forward.
