摘　　要：利用岩屑进行地应力测量的关键是将二次筛分的岩屑在实验室进行压实 ,以恢复到地层应力状态 ,同时测量有关数据 ,进而求出岩石的泊松比。讨论了地应力的计算模型及相关系数的确定方法。所测地应力与现场水力压裂资料反算结果基本一致。The key of measuring the earth stress by using rock cuttings is to compact the secondary sieving cuttings in laboratory so as to reconstruct the earth stress condition, at the same time the related data are measured, and consequently Poisson's ratio of rock is derived A model for calculating the earth stress and a method for calculating the correlation factors are discussed The measured earth stress is basically consistent with the result from inverse calculation by using the data of field hydraulic fracturing
