摘　　要：本文以镇泾油田为例,通过波速各向异性法及粘滞剩磁法对其地应力方向进行确定,同时,利用差应变分析法对研究区地应力大小进行测量。研究结果表明:镇泾油田平均水平最大主地应力为北东81.6°,梯度为0.0198MPa/m;平均水平最小主应力方向为北东171.6°,梯度为0.0161MPa/m。In this paper,the direction of in-situ stress of Zhenjing oilfield is determined by the wave velocity anisotropy method and the viscous remanence method.The magnitude of the in-situ stress in the study area is measured by differential strain analysis.The results show that the average maximum stress of Zhenjing Oilfield is 81.6°northeast,and the average gradient is 0.0198MPa/m.the direction of average minimum principal stress is 171.6°northeast,and the average gradient is 0.0161MPa/m.
