摘要
在公山庙构造古构造应力场数值模拟的基础上 ,结合岩石强度理论 ,计算出储集层岩体破坏接近度系数 η;将该值与现有井的实际生产资料对比分析 ,确定不同裂缝发育级别及其对应的 η门槛值 ;利用此标准 ,并运用岩石力学与构造地质学理论 ,结合野外裂缝观测结果 ,以及现场实际生产资料等 。
The proximity coefficient of destructiveness of rock in the bottom layer of Shaximiao reservoir can be calculated basing on numerical simulation of the palaeotectonic stress field in Gongshamiao structure and the theory of rock strength. This coefficient and the productive materiel of oil wells have been comparatively analyzed, then the threshold level of the coefficient and the corresponding grade of the fracture development have been confirmed. Appling this standardization and the theory of lithomechanics and structural geology, combining the observation about fracture in the field and the productive materiel etc., a comprehensive analysis and prediction of the developmental situation of fracture in the bottom layer of Shaximiao reservoir have been made.
