微乳液驱油技术强化石油采收率的研究进展

Review of the Microemulsion Flooding to Enhanced Oil Recovery

近年来,随着经济社会的发展,对石油的消耗量日益上涨,因此,如何提高石油产量的日益成为研究热点。微乳液驱油技术是提高油田采油产量最重要的技术之一,可大大的降低油水界面的表面张力和含油岩层的湿润度。本文介绍了微乳液的结构和组成,对不同种类微乳液的类型及特点进行了阐述,同时探讨了微乳液的驱油机理。

In recent years,with the development of society and economy,the consumption of oil increases increasingly.Therefore,efficient and low- cost improving the oil recovery technique has been becoming global research hotspots. It is generally known that the microemulsion flooding is a important technique to enhance oil recovery owing to its ability to reduce interfacial tension of oil and water and increase the wettability of reservoir rocks. This paper introduces the kinds and features of microemulsion. Meanwhile,the mechanism of the microemulsion flooding to enhanced oil recovery was also discussed.
