新疆准东煤田复杂地层钻进技术

Drilling Technique for Complex Formation in Zhundong Coalfield of Xinjiang

摘要:

新疆准东煤田库兰喀孜干矿区地层复杂，容易发生套管跑管、断管、孔壁坍塌、孔斜等孔内事故，给钻探施工带来较大难度。结合工程实际，介绍了该矿区复杂地层钻进较为成功的技术措施和基本做法。

Abstract:

Drilling construction is difficult in complex formation of Zhundong coalfield of Xinjiang with case moving, case broken, borehole wall collapse and borehole deflection. The paper introduced the effective technical measures and operation for complex formation in this mining area with engineering case.
