摘　　要：为了研究裂缝性砂岩油藏中油水渗流规律以及裂缝对油田开发的影响,利用岩石薄板模型,对6种不同裂缝形态下平行裂缝对水驱油过程进行了物理模拟,通过对水驱油效果的分析比较,得出了不同裂缝形态下水驱油渗流规律;根据裂缝性砂岩油藏的储层特点,建立了裂缝性砂岩油藏渗流等效连续介质模型,利用数值模拟的手段,研究了裂缝性砂岩油藏水驱油特征以及裂缝形态对开发的影响;通过物理模拟和数值模拟结果的对比,验证了等效连续介质模型在裂缝性砂岩油藏渗流模拟中的适用性。In order to study the fluid flow in fractured sandstone oil reservoir, rock slice model is employed in the physical simulation of the water-flooding procedures of 6 models with different fissure modalities. By analyzing the physical simulation results, some beneficial laws are obtained. Based on the characteristics of fractured sandstone reservoir, equivalent continuum model for simulating fluid flow is put forward. According to the continuum model, the oil and water flow in the 6 fissure models is studied by numerical simulation. The applicability of the equivalent continuum models for fluid flow simulation in fractured sandstone reservoir is verified by comparing the numerical simulation results with the physical simulation results.
