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.
