Abstract:
Carbon capture, utilization and storage (CCUS) technology is one of the most important means to combat climate change and achieve the goal of carbon neutrality. Among them, carbon dioxide captures with enhanced oil recovery (CCUS-EOR), as a core application form of CCUS, has the dual benefits of reducing carbon emissions and enhancing oilfield recovery. Based on typical CCUS-EOR project cases at home and abroad, combined with cutting-edge literature, this paper systematically analyzes the characteristics, current status and future development direction of the CCUS-EOR industry. It focuses on the mechanism of CO
2 oil drive, the core link and the current status of its application, and introduces in detail the latest progress of domestic and foreign cases and their achieved results. Combined with the requirements of China’s “dual-carbon” policy, this paper further evaluates the role of policy support in promoting the development of CCUS-EOR technology. The results show that in terms of economic benefits, the costs of CCUS-EOR projects are mainly concentrated in CO
2 capture and transportation, while the benefits are closely related to the increase in oil volume, oil price and carbon trading price. By analyzing typical project cases at home and abroad, the successful experiences of each project in terms of technology application, economic returns and policy support are summarized. Currently, the potential for the promotion of CCUS-EOR in China is enormous. The main bottlenecks it faces are the insufficient industrial infrastructure and the lack of policy incentives. In the future, with the gradual improvement of the carbon market, the continuous advancement of technological innovation, and the increased strength of policy incentives, CCUS-EOR will have a broad application prospect and is expected to become an important pillar for promoting global carbon reduction and energy security. Through the integrated development of policy support, technological research and development, and infrastructure construction, China is expected to bridge the gap in technological maturity and large-scale application, and further enhance the economic benefits and promotion feasibility of CCUS-EOR.
