应用水压致裂法测量三维地应力的几个问题
SEVERAL PROBLEMS IN APPLICATION OF HYDRAULIC FRACTURING METHOD TO IN-SITU 3-D STRESS MEASUREMENT
【摘要】 以新疆某抽水蓄能电站地下厂房区地应力实测资料为基础,探讨了当前应用水压致裂法测量三维地应力存在的几个问题,提出了孔壁出现倾斜水压破裂时计算三维地应力的简便方法,并对水压致裂三维地应力测量方法的应用前景进行了讨论。
【Abstract】 Several problems are investigated, which exist in the in-situ 3-D stress measurement by hydraulic fracturing at the underground powerhouse area of a pumped storage power plant in Xinjiang. A simple way is presented for stress determination when inclined hydraulic fracture occures on the borehole wall, and the application prospects are discussed of the hydraulic fracturing method for in-situ 3-D stress measurement in the future.
