摘要
基于彬长矿区DFS-M85-H井目标煤层的地质条件和物理力学性质,在对地层适应性分析的基础上,将充气欠平衡钻进技术应用于DFS-M85-H井水平段施工中,解决了低压储层护壁堵漏与储层保护的矛盾。通过环空压力波动控制的现场试验,实现了钻进过程安全、高效,为低压储层矿区类似工程的施工提供了有益经验。
Based on the geological condition and the physical and mechanical properties of the target coalbed of the well DFS-M85-H,after the analysis of formation adaptability,aerated underbalanced drilling technology has been applied in the horizontal section drilling of well DFS-M85-H for the contradiction between the loss plugging and the reservoir protection.The filed test for the control of the fluctuation of the bottom hole pressure,which improved the safty and efficiency of the drilling process a lot,has been carried out.This application has accumulated valuable experience for similar projects,especially for low pressure reservoir.
