Abstract: The carbon capture, utilization and storage (CCUS) are important options to reduce CO₂ emissions in a deeper way in response to climate change. In the past decade, important progress has been made in CCUS technology and industry, especially in China. Based on the research and practical experience of CCUS in recent years, the situation of CCUS technology types and the CCUS development deployment in China are described. The development history and project situation of enhanced oil recovery CCUS (CCUS-EOR) technologies in key global regions, as well as different CO₂flooding types and characteristics, and CCUS-EOR supporting technologies with Chinese characteristics are analyzed. The main influencing factors of CCUS-EOR sustainable development are analyzed systematically. On this basis, the development conditions of CO₂ flooding in China and the U.S. are compared, and the difficulties in promoting CO₂ flooding technology in China are pointed out. Finally, from the aspects of development basis, the main tasks, priority areas, project operation, policies, and regulations, specific suggestions for the sustainable development of China’s CCUS-EOR industry are put forward to provide necessary decision-making references for CCUS policy-making departments.
