表面活性剂提高采收率技术的进展

Progress in EOR by means of surfactants

阐述了表面活性剂提高采收率相关技术,包括表面活性剂驱、二元复合驱、三元复合驱,特别强调表面活性剂在复合驱中的应用;讨论了表面活性剂的种类、结构和性能;简述了表面活性剂在国内外的矿场试验结果。表面活性剂驱在技术上可行,降低驱油剂成本对该项技术的发展具有非常重要的意义。

This paper introduces the technologies of EOR （Enhanced Oil Recovery） related to surfactants, including surfactant flooding, surfactant-polymer flooding, alkaline-surfactant-polymer （ASP） flooding and the application of surfactants in the flooding; discusses the types, constitutions and performances of surfactants; and describes the field test results of chemical flooding with surfactants worldwide. It is shown that the chemical flooding with surfactants are technically feasible for many oilfields and the reduction of the cost of chemicals is important for the development of the technologies.
