摘要
Surfactant-polymer (SP) flooding has been proved to be an effective enhanced oil recovery method. Producing ultra-low interfacial tensions is an important mechanism relating to SP flooding for enhanced oil recovery. The interfacial tension between surfactant (PJS-1 and BE)/polymer solution and Simsim oil was evaluated in the work. The influence of surfactant and polymer concentration on interfacial tension between Simsim oil and these solutions is discussed. The interfacial tension between the oil and the surfactant solution reduces as the surfactant concentration increases. In the same concentration of surfactant, the interfacial tension between the surfactant solution and the oil becomes larger when the polymer was added in the solution.
