摘　　要：采用砂岩微观孔隙模型并模拟实际储层流体条件进行油驱水试验,观察研究了油驱水过程和残余水形成机理,测定了模型渗透率及油驱水入口压力,统计了模型残余水饱和度,并进一步分析了残余水饱和度、油驱水入口压力与渗透率的关系。Experiments are conducted on displacement of water with oil by using microscopic sandstone model and simulating actual reservoir fluid conditions, the process of water displacement and residual water forming mechanism are investigated, the simulated permeability and inlet pressure of water displacement are detected. Statistics on the residual water saturation is made and the correlation between saturation, the water displacement inlet pressure and permeability are further analyzed.
