碱－表面活性剂－聚合物（ASP）三元驱油技术的研究进展

摘要

On the strategy of the exploration , most of oil field in the world use the methods of water flood , which are low efficient and can only exploit about 20%~30%of the pool of oil.Recently , with the exhausted petroleum resources and the rise of international oil price , the need of the new flooding technology is imperative in order to increase oil productions.ASP ( Alkaline/Surfactant/Polymer) flooding is one of such techniques that has been proven successful due to its ability to improve displacement and sweep efficiency.Although this technology is still in laboratory and pilot stage , it has attracted much attention of researchers due to its higher the oil displacement efficiency and good application prospects.The status of research and application of ASP flooding technology were analyzed and summarized , and the limitations of the ASP flooding technology and technical solutions were also discussed.%当前世界上的油田基本都采用注水的驱油方式进行开采，但注水驱油的方式开采效率低，一般仅能开采20％～30％左右的地下油藏。近年来，随着石油储量的日益枯竭以及国际油价的上涨，为提高石油产率，采用新的驱油技术进行开采已势在必行。三元驱油技术采用碱－表面活性剂－聚合物（ ASP）作为驱油剂，综合三种化学驱油剂优点，使之协同发挥作用所形成的一种新型化学驱油技术。尽管碱－表面活性剂－聚合物（ ASP）驱油技术还处于研发与小试阶段，但其驱油效率高，具有良好的应用前景，引起了研究者的广泛注意。本文对碱－表面活性剂－聚合物（ ASP）三元驱油技术研究与应用现状进行了分析与总结，同时讨论了该技术的缺陷及相关的解决方案。
