摘要
本文综述了采用乳化筛选试验法制作活性图,对碱-助表面活性剂-聚合物(APS)驱油体系相性质所作的研究。讨论了活性剂、碱对体系相性质的影响及相性质与界面张力、驱油效率之间的关系。在碱-原油体系中加入低浓度表面活性剂可使活性区加宽,体系最佳含盐量提高。过量碱在体系中起电解质作用。一价阳离子对相性质的影响次序为 K^+>Na^+>NH_4^+。最佳体系的界面张力可达到很低值。
This review article summarized comprehensively the recent situation of phase beha- vior investigations for alkaline-cosurfactant-polymer(ASP) flooding systems.The following topics are covered: historical aspect,experimental methods for laboratory investigations,criteria for determing phase behavior,phase behavior as influenced by alkaline and surfactant,relations of phase behavior to flooding coefficiency and of interfacial tension to phase behavior.
