| 摘 要： | 在连续介质力学理论架构下,文章建立了饱和油水两相渗流与变形孔隙-裂隙双重介质耦合作用的理论来模拟裂隙砂岩储层中的油-水渗流,提出了基于双孔隙固相系统变形与油水两相渗流的全耦合力学模型;在对力学模型给予适当简化的基础上,应用解耦的有限元数值解方法对裂隙储层的两相流体压力、饱和度以及储层变形等参数进行了数值模拟;结果表明,裂隙储层流体运动主要由裂隙变形、油/水的PVT特性所决定。

| Abstract: | A coupled double-porosity model is presented based on continuum mechanics to simulate the oil-water flow in fissured sandstone reservoirs in this paper.The model is developed by fully coupling an extended geomechanical model with a double-porosity model for the two-phase reservoir flow.By introducing the assumptions to the governing equations,an uncoupled FEM numerical scheme is proposed,which describes the pressure,water phase saturation and solid deformation respectively.The numerical results show that the fluid flowing in fissured reservoirs is mainly controlled by the fissure deformation and the oil/water PVT property. |
