摘　　要：通过以二氧化碳(CO_2)为切入点,联合二氧化碳开发干热岩技术(CO_2-EGS)、二氧化碳驱油技术(CO_2-EOR)和二氧化碳封存技术(CCS),提出了二氧化碳抽热-驱油-封存一体化的强化采油技术。经过多方面分析,该技术具有很高的可行性和优越性,同时该技术也是对CCUS技术的有益补充,这对节能减排具有重大的意义。Taking carbon dioxide as the starting point and combining with CO2-enhanced geothermal systems （ CO2- EGS） ,CO2-enhanced oil recovery （CO2-EOR） and CO2 capture and storage （CCS） technologies, an integrated technology about enhanced oil recovery is proposed in the mode of CO2 extracting heat-oil displacing-storage. Through analysis in various aspects, it is verified that this technology has high feasibility and superiority. At the same time, this technology is also a useful supplement to CCUS technology, which plays an important role in energy conservation and emission reduction.
