| 摘 要： | CO2温室气体使全球气候变暖，温度幅度已经超出了其本身自然变动的范围，对人类的生存和社会经济的发展构成了严重威胁。CO2的地质处置最有效的方式就是注入油气田，不但封存了CO2，而且还可提高油气田的采收率，国外注CO2驱提高原油采收率技术已在低渗透油藏中得到了广泛应用。针对中国低渗透油藏自然产能低、地层能量不足、地层压力下降快等引起采收率低的现状，在分析CO2混相和非混相驱提高采收率机制的基础上，系统整理和归纳了CO2驱油技术中混相驱和非混相驱两种作用方式的研究现状。通过国内外低渗透油藏注CO2驱提高采收率应用情况分析指出，CO2作为一种有效的驱油剂，CO2驱能得到明显的增油降水和提高采收率的效果，总结了目前需要解决的主要问题，提出应积极开展注CO2驱油技术的研究和现场试验的建议，并对CO2驱油技术的发展前景进行了展望。

| Abstract: | The global warming is accelerating due to huge amount of greenhouse gas emission of CO2 which leads to the temperature rise and the climate change on the earth.Global warming has put much pressure on both human being survival and social economy development.The most effective way for disposing CO2 is to directly inject them into oil and gas fields,and only in this way,not only CO2 could be sealed up but also the recovery rate of oil and gas fields could be enhanced.CO2 flooding Enhanced Oil Recovery(EOR) tec... |
