摘      要：CO_(2) capture is a process with a high energy consumption,and its large-scale implementation should be based on comprehensive analysis of its impact on the energy,economy,and *** process of injecting CO_(2) into existing oil fields is a well-known enhanced oil recovery(CO_(2)-EOR)*** CO_(2) as a working fluid to recover oil can compensate for the energy consumption of the capture and transport processes,increasing the feasibility of CO_(2) capture while achieving carbon *** this study,a full-chain CO_(2) capture,utilization,and storage(CCUS)system based on the post-combustion capture method is deconstructed and coupled.A full-chain energy consumption calculation software is developed,and optimization analysis of the energy consumption system is *** energy budget of the oil displacement utilization is deconstructed,and the advantages of the water alternating gas(WAG)method are clarified from an energy budget point of *** analysis reveals that the benefits of CO_(2)-EOR are far greater than the energy consumption of other CCUS processes,and CCUS-EOR is a CO_(2) utilization method with positive energy *** on the simulation of the effects of N_(2) and CH_(4) on the recovery factor,a multi-well combined injection-production method is proposed,and the reasons for increasing profit are analyzed.
