摘要: 系统研究了五种驱油表面活性剂和三种胜利原油的动态界面张力性质, 考察了表面活性剂浓度对体系动态界面张力的影响。研究结果表明, 在弱碱性条件下, 原油中不同活性组分均能在界面上发生反应, 原位生成界面活性物质。外加表面活性剂、 原油活性组分及其界面产物间的相互作用决定了动态界面张力的特征行为, 表现
为“ L” 型、 “ V” 型和“ W” 型三类动态界面张力特征曲线。表面活性剂的结构、 浓度以及原油类型是影响动态界面张力特征的关键因素。

Abstract: The dynamic interfacial tensions between five types of EOR surfactants and three types of Shengli crude oils were investigated, and the effect of surfactant concentration on interfacial tension was explored. The experimental results show that the different active components in crude oil could react under alkalescent condition and produce the surfaceactive soaps at the interface in situ. The interactions among the added surfactants, active components of crude oil and their products at interface together determined the characteristic behaviors of dynamic interfacial tension. Three types of characteristic dynamic interfacial tension curve might manifest as type "L", type "V" and type "W". The structure and concentration of surfactant and the type of crude oil were key factors impacting on the dynamic interfacial tension characteristics.

Key words: EOR surfactant, Shengli crude oil, Oilwater interface, Dynamic interfacial tension, Alkali
