| 摘 要： | 针对三元复合体系,应用牺牲剂对油砂预吸附后,测定表面活性剂在油砂上吸附等温线,结果可降低表面活性剂吸附损失４０％￣６０％。界面张力和粘中度测量表明,牺牲剂加入对复合体系性质影响较小。牺牲剂无论是以前置段塞还是以混合方式注入都可以提高三元复合体系驱油效率,但以前置段塞注入效果为佳。

| Abstract: | According to ASP system, sacrificial agent is used to preadsorb oil sand and then to measure the isothermal line of surfactant on oil sand. The result shows that the adsorption loss of surfactant is reduced by 40%-60%. Interfacial tention and viscosity measurement shows that sacrificial agent has little affect on complex system characteristic. Both preslug and mixtured injection of sacrificial agent can improve ASP displacement efficiency, but preslug is better. |
