| 摘 要： | 针对试验获得多孔介质中油气水三相的渗流参数难度较大、经验模型预测不准确的问题,建立水湿油藏近混相状态下的三相渗流网络模型.利用孔隙级模拟方法分析三相渗流过程中可能存在的3种驱替过程,模拟再现不同的饱和路径,得到油气水三相相对渗透率.结果表明:在水湿油藏中,各种驱替结束后最终的油气水分布均为水相占据小孔隙,气相占据大孔隙,油相占据中间孔隙;三相水湿体系中的水相相对渗透率只是含水饱和度的函数,气相相对渗透率和油相相对渗透率小仅与各自的饱和度有关,还与三相饱和历史有关.

| Abstract: | It is difficult to get the parameters of oil-gas-water three-phase flow in porous medium using experimental methods,and the present empirical models are usually not very accurate. In view of the above problem,a three-phase fluid flow network model for water-wet reservoir at near-miscible condition was established. The possible three displacement processes in three-phase flow were analyzed by using pore-scale modeling method. The three-phase relative permeability was obtained by simulating different saturati... |
