| 摘 要： | 利用古构造应力场二维数值模拟,预测研究区沙河子组岩体的破裂程度,分析古构造应力分布特征,划分裂缝发育级别。预测结果表明,十屋油田沙河子组储层裂缝主要发育在断层位置及其附近地区,储层经历两期构造应力场作用并形成了2期4组裂缝,裂缝主要发育的方向为北东向和南北向。

| Abstract: | Through a combination of structural geology,rock mechanics and production.We can use two-dimensional numerical simulation of tectonic stress field,predict the rupture extent of the study area Shahezi rock,calculate the the Shahe sub-group of rock rupture close to extent,make sure the rock rupture the relationship between the degree of fracture development.The prediction results show that Shiwu Oilfield Shahezi reservoir fractures developed in the fault location and the surrounding area,reservoir has experienced two tectonic stress field and the formation of two stages(four groups)cracks,and the cracks in the main direction of development for the NE and SN. |
