摘　　要：二氧化碳驱提高石油采收率技术作为一种提高经济效益、降低温室气体排放的手段,具有良好的实际应用前景。但是我国油田多属陆相沉积,原油和CO2的最低混相压力过高,这是制约二氧化碳驱提高石油采收率技术在我国发展的重要因素,因而研制有效的助混剂尤为关键。本文综述了国内外关于CO2-原油助混剂的研究现状,从基团类别、分子构架和应用效果三个层面考察分析,总结出高效的CO2-原油助混剂分子结构中需含有多个亲CO2基团和多个亲油基团。同时提出,在有效控制成本和防止环境污染的前提下,研制稳定高效的CO2-原油助混剂体系是目前二氧化碳驱提高石油采收率技术的关键突破口。CO2 flooding for enhanced oil recovery(CO2-EOR)is a promising technology to promote economic efficiency and reduce green-house gas emission. However,oil field in China usually formed by continental deposit,resulting in high minimum miscible pressure(MMP)and impeding the application of CO2-EOR in China. Therefore,the research on efficient CO2 flooding miscible assistants becomes vital. This review demonstrated several examples of miscible flooding assistants from China and other countries, analyzed from aspects of group category,molecular skeleton,assistant effect,and concluded that effective flooding miscible assistants should consist of multiple CO2-philic and oleophylic groups. Meanwhile,this article pointd that on condition of controlled cost and environmental sustainability,stable and effective flooding miscible assistants would be the key breakthrough for application of CO2-EOR in China.
