摘　　要：根据等效思想,给出了裂缝性砂岩油藏等效渗透率张量和变形场等效力学参数的计算方法,建立了油藏渗流和变形的等效连续介质模型;通过分析渗透率与应变之间的耦合关系,得到了裂缝性砂岩油藏流固耦合渗流计算的数学模型,并给出了计算方法.实例应用验证了所建模型的正确性.研究成果对认识裂缝性砂岩油藏的渗流规律有重要意义.Based on the equivalence concept, a method has been developed to calculate the equivalent permeability tensor and deformation parameters in fractured sandstone reservoir, and an equivalent continuum model has been established for reservoir seepage flow and deformation. By analyzing the coupling relationship between permeability and strain, a mathematical model and methods are deduced for calculation of fluid_solid interaction flow in fractured sandstone reservoir. The model accuracy has been confirmed by a case study. All these results are important to understanding the seepage flow in fractured sandstone reservoir.
