从表面活性剂分子量、表面活性剂浓度、电解质浓度、 烷烃碳数等方面考察了系列烷基苯磺酸盐异构体纯化合物的油水动态界面张力行为。研究表明，表面活性剂分子量越大和电解质浓度增加使界面张力动态变化越慢，达到平衡所需时间越长；表面活性剂浓度增加和烷烃碳数增加使界面张力动态变化加快，达到平衡所需时间减少。

关键词: 烷基苯磺酸盐，动态界面张力，三次采油

The dynamic interfacial properties of alkylbenzene sulfonates with alkane were studied from many aspects, such as the weight of the surfactant, the carbon number of alkane, the concentration of alkali and the concentration of surfactant. The results show that with the higher of the weight of surfactant and the concentration of the electrolyte is, the more quickly of the interfacial tension changes, the less of the time balances. With the higher of the concentration of surfactant and the carbon number of alkane, the slower of the interfacial tension changes, the less of the time balances.

Key words: alkylbenzenesulfonate， dynamic interfacial tension, tertiary oil recovery
