摘要
通过以二氧化碳（CO2）为切入点，联合二氧化碳开发干热岩技术（CO2-EGS）、二氧化碳驱油技术（CO2-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。
Abstract
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.
