利用岩心分析测定、测井解释、压裂过程分析和微地震波法等多种监测手段，研究了地应力及裂缝特征。结合地应力场的数值模拟工作，描述了地应力与裂缝的分布以及二者之间的关系。结合油井动态和分析还发现，地应力的大小与油气富集程度，尤其是单井初期产量，有较好的线性关系。克拉玛依油田八区530井区下乌尔禾组，水平主应力及主裂缝方向为东西向，中都低应力区为初期产量较高的部位。
Using the methods of core analysis, logging interpretation, fracturing analysis and microseismic method, the authors have studied the characteristics of in-situ stress and fracture. Combined with the numerical simulation of geostress field, the distribution of earth stress and fracture and the relationship between them are described. Combined with the well dynamics and analysis, it is also found that the magnitude of geostress has a good linear relationship with the degree of hydrocarbon enrichment, especially the initial output of single well. The Lower Wuerhe Formation in Well 530 of Block 8 of Karamay Oilfield shows that the horizontal principal stress and main fracture direction are east-west direction, while the middle-low stress region is the part with high initial yield.
