| 摘 要： | 本文依据物理界面层模型讨论了表面活性剂溶液的润湿现象,提出了润湿系数表征表面活性剂在多孔介质孔隙表面的润湿能力,并研究了润湿系数的计算方法。以十二烷基苯磺酸钠溶液为例,研究了表面活性剂溶液在多孔介质中的润湿性。在非超低界面张力条件下,实验验证了表面活性剂溶液的界面润湿性改善石油采收率的能力,实验结果表明表面活性剂在多孔介质中的润湿性对洗油效率起着重要作用。

| Abstract: | According to the interface layer model of physical interface,wetting coefficient is proposed to measure the wetting ability of surfactants on the surface of porous media and its calculating method is discussed.The wettability of surfactants on the surface of porous media is studied using SDBS.When interfacial tension is not so low,the effects of wettability on oil recovery were studied by experiments.The results showed that the wettability of surfactant on the surface of porous media play a very important r... |
