Abstract: The binary complex system was composed of the sulphonate Gemini surfactant and the hydrophobically associating polymer at different ratios. Viscosity and interfacial tension were measured before the core flood experiments. After injecting the binary system at different surfactant/polymer ratios and injection phase, the viscosity, interfacial tension, and concentrations of the polymer and the surfactant in the effluent collected at different positions of the long core were measured. Furthermore, the static and dynamic adsorptions of the system were measured. Finally, the variation law of physicochemical properties of surfactant/polymer binary complex system in porous media was obtained. [Received: November 17, 2015; Accepted: July 17, 2016]
