摘　　要：以制备耐高温高盐的泡沫复合驱油体系为主要目的,研究了不同配比的非离子表面活性剂烷基多糖苷(alkyl polyglycosides,APG)和咪唑啉两性表面活性剂(2-Undecyl-N-Carboxymethyl-N-Hydroxyethyl Imidazoline,LC)复合体系在高温高盐条件下的界面张力、泡沫量和泡沫稳定性等,并用SVT20N旋转滴界面张力仪分别测定了不同配比的APG-LC复合体系在不同浓度时的油水界面张力.实验结果表明,APG与LC的配比会直接影响体系的界面张力,当其配比为6∶4且质量分数为0.3时,油水界面张力达到最低值.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.
