Abstract: For the preparation of a foam flooding system in the presence of high content of salinity at high temperature, alkyl polyglycosides (APG) and 2-Undecyl-N-Carboxymethyl-N-Hydroxyethyl Imidazoline (LC) system was investigated at different concentrations and proportions. Foam properties such as interfacial tension(IFT), foamability, and foam stability were measured. Oil-water IFT of the APG-LC system was measured with the spinning drop method on SVT20N at different ratios of APG and LC with different concentrations, respectively. The results showed that the ratio of APG and LC directly affects IFT of the blend system. When the ratio of APG and LC was 6∶4 and mass fraction of the blend system was 0.3%, the IFT was minimum.
