二次采油与三次采油的结合技术及其进展

Combination of Secondary Oil Recovery and Tertiary Oil Recovery and Its Development

部分主力油田在较长一段时间的持续开采后,进入高含水开发期,在此阶段要继续保证主力油田原油开采效率和开采企业的整体效益,需要将在提升系数机理方面具有明显优势的二次采油技术和在提升洗油效率方面优势突出的三次采油技术有机结合,在此背景下,针对二次采油与三次采油的结合技术展开研究,为主力油田提升原油生产效率提供参考。

Some of the main oilfields will enter high water-cut development period after continuous exploitation for a long period of time.In this stage,it is necessary to continue to guarantee the crude oil extraction efficiency of main oilfields and the overall benefit of mining enterprises.It is necessary to have obvious advantages in raising the coefficient mechanism.Secondary oil recovery technology and the tertiary oil recovery technology which has the outstanding advantages in enhancing oil washing efficiency.Under this background,this paper studies the combination technology of secondary oil recovery and tertiary oil recovery,which can provide reference for upgrading crude oil production efficiency.
