摘　　要：SURFACTANT-POLYMER flooding has received much attention recently because it is an efficientpetroleum recovery process. The optimum efficiency is due to its ability to improve the charac-teristics of the interface between the solid surface of the micropores of cores, the ground wa-ter, and oil included in the oil reservoirs. Surfactant molecules aggregate in water solution canallow ultra low interfacial tension (IFT) between oil and water to be achieved so that oil pro-duction is favorable. Nuclear magnetic resonance (NMR) measurement provides informationabout Brownian movement of various kinds of molecules in solution of multicomponent,
