By physical simulation experiments, the features of alkali-free binary flooding system (polymer and a new surfactant BS) were contrasted with weak base ternary flooding system and alkali ternary flooding system. The experiment results showed that interfacial tension of BS binary system is the lowest. In the absence of alkali, the viscosity and elasticity of binary system were higher than those of other two ternary flooding systems. By physical simulation experiments with artificial heterogeneous cores, the recovery of BS binary flooding system was 2 percent higher than that of weak base ternary flooding system, and 1.4 percent higher than that of alkali ternary flooding system.
