摘要(Abstract)：

介绍了近年来国外针对润湿反转作用提高采收率的研究进展.首先介绍了一种测定润湿角的方法——双滴双晶法(DDDC).对比了近几年国外常用的几种润湿反转剂.研究表明:阳离子、阴离子以及非离子表面活性剂在有效作用浓度以及作用机理上存在明显区别.综合各种试验结果,认为含有聚氧乙烯(丙烯)基的阴离子或是非离子活性剂具有较好的应用前景.最后通过分析固体表面润湿反转导致的油珠剥离过程,以及不同阶段的力学变化规律,发现润湿反转作用主要受到固液界面张力的影响,而油水界面张力并不是决定性的影响因素.因此,有必要进一步研究表面活性剂对固液界面张力的影响规律.

关键词(KeyWords)： 润湿反转;表面活性剂;润湿性
