摘要
对二氧化碳驱油机理的研究,是揭示二氧化碳驱高效开发各类低渗透油田的基础。通过对国内外文献资料的调研,详细论述了二氧化碳近混相驱的机理和过程,介绍了影响二氧化碳近混相驱的因素并且通过数值模拟计算各因素对开发效果的影响,提出了二氧化碳近混相驱研究中存在的问题,进而为二氧化碳驱提高采收率技术的高效、合理开发奠定理论基础。
The mechanism research of CO2 flooding is the foundation of efficient development of CO2 flooding for EOR in low permeability reservoirs. The mechanism and process of near miscible CO2 flooding are discussed in detail. The influencing factors as well as problems among the research are given. The influence of the factors is calculated using numericalmodeling. These can help to provide a theoretical foundation for the efficient,rational exploitation of near miscible CO2 flooding.
