| 摘 要： | 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。

| Abstract: | This paper studied the characteristics of ground stress and fracture by applying core analysis, logging interpretation, fracturing analysis and micro seismic wave method, discussed the distribution of ground stress and fracture and their relation, along with numerical simulation over ground stress field. Based on oil well performance analysis, it is further found that ground stressess has linear relation to oil/gu enrichment, particularly initial production of single well. It is concluded that horizontal major stress and major fractare appear in E-W direction, and low stress stress area in central part has higher initial production in lower Wuerhe formation in 530 well area, District No. 8 in Karamay oilfield. |
