Aqueous foam is widely used in oil drilling, oil displacement, mineral flotation and so on; however, the foam belongs to an essentially thermodynamically unstable system. Based on the synergy of different surfactants, the foaming ability and stability of their mixtures were investigated through Waring Blender method, and an aqueous foam system with high stability, named as AFS-2, was screened out. And then, its microstructure was observed, and its oil-sensitivity and salt-sensitivity were evaluated. The experimental results showed that the best system AFS-2 was composed of 1 g/L SDS, 1 g/L 3#, 3 g/L PAM, 3 g/L SF-1 and 3 g/L dodecanol. The volume of AFS-2 foam generated by its 100 milliliters solution was 380 milliliters at 20℃, and the bubbles are round, and their diameters are distributed within the range of 10～100 μm. The half-life period of the system was 6050 minutes which meant that the AFS-2 system had high stability. Three kinds of oils, including 0# diesel, Tahe heavy oil and Fengcheng super-heavy oil, could strongly destroy the foam. At the same time, the higher the oil viscosity, the weaker the damage capability to the foam. When the concentration of Fengcheng super-heavy oil wais less than 10.6 g/L, half-life period of the system was more than 3720 min. When the concentrations of CaCl2 and NaCl were less than 1 g/L and 10 g/L, respectively, AFS-2 foam system could maintain adequate stability.
