中文摘要： 三次采油中，表面活性剂驱油技术是开采现有石油资源的有效途径之一。然而，表面活性剂及其混合体系不太高效的性能，例如，表/界面活性不高，与高矿化度地层水的配伍性不佳，成为制约该项技术推广应用的主要瓶颈。本课题拟以氨基磺酸型两性表面活性剂与传统表面活性剂的二元混合体系为研究对象，对盐水中二元混合体系协同增效机理进行基础科学研究。利用表/界面测量、荧光探针、电导测量和核磁共振等技术手段，探索盐水中表面活性剂二元混合体系协同性能，揭示无机盐等与混合体系分子间的作用规律，建立理论模型和数学表达来描述分子间相互作用关系。本项目的成功开展，必将为高效性能的表面活性剂配方体系设计、性能预测及应用提供理论和技术依据。

英文摘要： In EOR, surfactant flooding may be one of the most effective solutions to recovery the petroleum resources available all over the world. However, the main bottleneck of application and dissemination for surfactant flooding may be the bad properties of surfactants or their mixtures, e.g. the inefficient surface/interfacial activities, the bad compatibility of surfactants with reservior water (specially including high concentration of inorganic ions), and so on. Taking the binary mixtures containing both amino sulfonate amphoteric surfactants (ASA) and a traditional surfactant as the object of this investigation, the basic science about the mechanism on synergistic effect of the surfactant mixtures systems in brine will be investigated in the present project. The synergistic properties between ASA and other surfactants in brine will be characterized by the technologies of surface/interfacial measurement, fluorescence probe, conductivity measurement, NMR, and so on, which will clarify the mechanism on interaction between inorganic salts and surfactants in the binary mixtures. And then the relationships of the interaction between the molecules will be described by the theoretical models and the mathematical equations established. Once this project be successfully completed, it is of great significance theoretically
