摘　　要：在用稳定法测定三元复合驱油体系与油的相渗曲线时，用聚合物分子滞留条件下的碱、表面活性剂体系（ＡＳ）与油的相渗曲线来代替ＡＳＰ驱油过程中的相渗曲线。研究了聚合物分子在孔隙介质中的滞留程度、体系的界面张力对相渗曲线的影响，将聚合物的作用归结为对不可动水相饱和度、油水相的相渗曲线高低的影响；将碱和表面活性剂的作用归结为通过降低界面张力来影响残余油饱和度及水相相渗曲线的高低，得出了聚合物的滞留程度与不可动水相饱和度、油水相端点相对渗透率值之间的关系曲线和界面张力与残余油饱和度、界面张力与水相端点相对渗透率之间的关系曲线。The relative permeability curve of ASP/Oil system was obtained by measuring that of AS/Oil system using steadystate method after polymer retention. The effect of polymer retention and interfacial tension on the relative permeability curve was investigated. The results shows that polymer mainly increase the irreducibl e water saturation while decreasing the height of relative permeability curves f or both water and oil phases; alkali and surfactant mainly decrease the resid ual oil saturation while increasing the height of relative permeability curve fo r water phase. The experiments indicated the relations between polymer retention and irreducible water saturation, endpoint relative permeability reductions f or water and oil phases, and that between interfacial tension and residual oil s aturation, endpoint relative permeability for water phase.
