Discussion on Drilling in Complex Strata with Managed Pressure Drilling

摘要:

利用控制压力钻进技术有效解决了姚庄煤田石千峰组砂岩涌水、砂泥岩坍塌问题，对提高钻进效率、降低施工风险起到了重要作用，为今后该区钻探施工提供了借鉴经验。

Abstract:

Water-gushing in sandstone and sand-shale collapsing were effectively solved by managed pressure drilling technology in Yaozhuang coalfield, which played important role in improving drilling efficiency and reducing construction risk. The practice provided the construction experience for drilling in this area.
