摘　　要：以水压致裂原地应力测量实际测试结果为例,通过对测试记录曲线及地应力计算结果的分析,结合破裂的印模定向和钻孔超声波测试结果,讨论和分析了原生裂隙对水压致裂原地应力测量结果的影响,并对相关的数据处理方法提出了合理的建议。In this paper, practical test results of in situ stress measurements of hydraulic fracturing being taken as examples, by analysis on test record and calculation results of in situ stress, combined with the packer impression and acoustic imaging test results, the influence of pre-existing fracture on the results of in situ stress measurements of hydraulic fracturing was discussed and analyzed, and also reasonable suggestion for relevant data processing method were presented.
