摘要

控压钻井 (Managed Pressure Drilling) 是一种井控新技术, 在安全密度窗口窄、多套压力系统和压力敏感性地层应用卓有成效。本文总结了控压钻井技术的基本原理和各类应用场景, 以顺北区块A、B和C井为例, 分析了控压钻井技术在处理窄窗口地层钻井、溢流、井漏等复杂情况的优势点, 提出控压钻井关键设备、配套技术和常见异常处理方法。得到如下结论: 控压钻井技术的应用为顺北区块的高效开发提供了保障, 提高了顺北区块钻井质量和钻井效率。研究结果能够有效指导控压钻井作业, 保障井控安全, 丰富超深井钻井技术理论。

Abstract

Managed Pressure Drilling (MPD) is a kind of new drilling technology that has been effectively applied to pressure-sensitive formations of narrow safety density windows, multiple pressure systems. This paper summarizes the basic principles and various application scenarios of MPD technology. Taking Well A, Well B and Well C in Shunbei block as examples, the advantages of MPD technology in dealing with complex situations such as drilling, overflow and leakage in narrow density window formations are analyzed, and the key equipment, supporting technology and common abnormal treatment methods of MPD are proposed. The conclusions are as follows: MPD technology, . The application of MPD has provided a guaratee for the efficient development of the oil fields in Shunbei block and improves the drilling quality and efficiency of the block. The research results can effectively guide the managed pressure drilling operation, ensure the safety of well control, and enrich the theory of ultra-deep well drilling technology.
