磺酸盐型表面活性剂界面性能影响因素研究

Study on influencing factors for interface properties of sulfonate surfactant

在三次采油中,表面活性剂降低油水界面张力是驱油的主要原理之一。为了能够清楚地逐一研究表面活性剂体系各因素对界面行为的影响,本文采用一种磺酸盐型表面活性剂以及结构组成明确的模拟油(烷烃),探讨各因素对界面张力行为的影响。

In EOR, the ability of surfactant to reduce oil-water interfacial tension is one of the main mecha- nism of surfactant flooding .In order to clarify the effect of surfactant systems on oil-water interficial tension ,in this paper,a series of experiments were carried to investigate the influence of each factor on interfacial tension by using one kind of alkylbenzene sulfonates with unique structure and definite structure model oil（ alkanes ）.
