摘　　要：利用表面活性剂复配产生的协同效应降低油水界面张力和原油黏度,是近年来提高石油产品采收率的重要方法。不同油田开采的原油各组分质量分数不同,需要根据组分质量分数筛选适合的表面活性剂。研究了十二烷基苯磺酸钠(SDBS)和月桂基葡糖苷(APG1214)与辽河稠油的界面张力及其乳化性能;通过改变复配比、矿化度、pH研究界面张力,并对乳状液进行了黏度测量。结果表明,在表面活性剂复配体系中,加入适量的无机盐可以降低油水界面张力,形成较稳定的稠油乳状液。Using the synergistic effect of surfactant mixture to reduce oil-water interfacial tension and crude oil viscosity is an important method to improve oil recovery in recent years.The content of each component of crude oil produced from each oil field is different,so it is necessary to screen the suitable surfactant according to the component content.In this paper,the interfacial tension and emulsifying properties of sodium dodecyl benzene sulfonate(SDBS)and lauryl glucoside(APG1214)in Liaohe crude oil were studied by rotating drop interfacial tensiometer and bottle test method.The interfacial tension was studied by changing different compounding ratios,salinity and pH value,and the viscosity of the emulsion was measured by viscometer.The results show that the interfacial tension between oil and water can be reduced and the stable heavy oil emulsion can be formed by adding proper amount of inorganic salt in combination of surfactant.
