摘要： 井壁失稳是霍尔果斯背斜钻井过程中的普遍现象。地质和工程研究表明, 由于受构造运动的挤压, 霍尔果斯背斜地应力高, 地层破碎, 特别是高陡层理发育, 钻井过程中井下坍塌、漏失等复杂事故频繁。利用室内实验和水力压裂试验分析数据, 建立了适用于霍尔果斯背斜的地应力计算模型, 依据已钻井测井数据建立了霍10井区的地应力剖面及地应力分布, 为该地区井壁稳定性研究提供参考依据。

Abstract: Borehole unstability is one of the major problems that hamper the drilling in Huo'erguosi anticline. Comprehensive analysis of geological and engineering data indicates that, due to the extrusion of tectonic movement, the anticline features high in-situ stresses and broken formations, causing frequent borehole collapse and lost circulation problems. In this paper, in-situ stress models for Huo'erguosi anticline are put forward with the data from the core analysis and hydraulic fracturing test. Then, the in-situ stress profile and distribution of Wellblock Huo-10are established. They could be as guides for the borehole stability research in this area.

Key words: borehole unstability, tectonic movement, model, in-situ stress profile
