摘要(Abstract)：

为研究亲油多孔介质中残余油膜的微观运移机理,以毛细管渗流模型为基础,结合边界层理论,建立膜状残余油微观渗流模型.根据亲油多孔介质中膜状残余油的分布特征,推导毛细管中油、水微观运移方程;改进毛细管模型,推导不等径毛细管模型的油水相对渗透率表达式,得到相对渗透率曲线,分析毛细管半径、边界层厚度和流体黏度对相对渗透率曲线的影响.结果表明:随着毛细管半径增大,相对渗透率曲线向左逐渐平移;随着边界层厚度减小,相对渗透率曲线向左逐渐平移;随着油黏度增大,水相的相对渗透率曲线向右下方逐渐平移,油相的相对渗透率曲线没有变化.该结果对分析高含水期残余油渗流机理及提高采收率提供理论指导.
