考察了克拉玛依石油磺酸盐（KPS）、磺基甜菜碱（BS）、脂肪胺聚氧乙烯醚（FAPE）和十二烷基二甲基苄基氯化铵（1227）等4种表面活性剂的溶液改变含油天然岩芯砂模型表面可润湿性的能力和对新疆油田七东1区原油的静态洗油效率。分别将KPS，BS和FAPE与聚丙烯酰胺（KYPAM－2）组成二元复合体系，测试了KPS／KYPAM－2，BS／KYPAM－2和FAPE／KYPAM－2二元体系与1227溶液对原油的界面张力，并计算了它们剥离岩石表面油滴所需克服的粘附功，最后利用上述二元体系与1227溶液进行了驱油效率的考察。结果表明：4种表面活性剂溶液均能使岩石表面的可润湿性由油性润湿向中性或水性润湿反转；其中BS的粘附功为0.018 J，静态洗油效率为85.7％，BS／KYPAM－2二元体系水驱后提高采收率12.7％，在4种表面活性剂里性能最好。

The ability for changing lipophilic natural core model surface wettability and efficiency of static oil washing in East District 7(1)Xinjiang oilfield of four kinds of surfactant solution,Karamay petroleum sulfonate (KPS),sulfobetaine (BS),fatty amine polyoxyethylene ether (FAPE)and dodecyldimethylbenzylammonium chloride (1227 )were examined. Binary compound systems were composed separately using KPS,BS and FAPE with polyacrylamide (KYPAM-2 ). Then,interfacial tension against crude oil using solution of KPS/KYPAM- 2 ,BS/KYPAM - 2 and FAPE/KYPAM - 2 binary compound systems and 1227 solution was measured,and adhesion work needs to overcome for stripping the oil droplets from the rock surface by the binary compound system was calculated. Finally,oil displacement efficiency was studied using the above -mentioned binary compound systems and 1227 solution. The results showed that all of four kinds of surfactant solution can make the rock surface wettability reverse from oil-wetting to neutral wetting or aqueous wetting;where,the adhesion work of BS solution is 0.018 J;efficiency of static oil washing using BS is 85.7% and EOR magnitude after water flooding of BS/KYPAM -2 achieves 12.7%,which is the best among the four kinds of surfactant.
