摘要
以延长气田为例,通过分析LP-1井煤岩的组构、理化及力学特性,揭示了复杂煤层失稳机理,提出了钻井液技术要求和措施,并研发出了一套高性能水基钻井液。
Taking Yanchang gas field as an example, by analyzing the structure, physicochemical and mechanical characteristics of coal and rock in well LP-1, the mechanism of complex coal seam instability is revealed, and the technical requirements and measures for drilling fluid are put forward, and a set of high-performance water-based drilling fluid is developed.
