Abstract CO2 capture, utilization and storage (CCUS/CCS) is the most viable carbon reduction technology and the key technology for significantly enhancing the recovery rate of low-permeability reservoir. This paper summarizes the progress of CNPC’s CCUS mechanism research, supporting technology, equipment system, and field tests, analyzes the challenges faced by the whole industry chain of CO2 capture, transportation, oil displacement, and storage, and the development trend of the industry. It points out that the lowconcentration carbon source capture technology, regional cross-industry pipeline planning design, the great improvement of the recovery rate, and the safty of storage will be the main themes of future research. Predictions are made that CCS will enter the scale test stage and supporting policies will be issued. It proposes that CNPC is speeding up tackling key technologies, such as low-cost large-scale capture of low-concentration CO2, supercritical longdistance transportation, further improvement of recovery rate and storage rate, and safe large-scale storage. Lastly, based on the aspects of top-level design, industrial clusters, fiscal subsidies, project operation, and policies and regulations, it proposes specific suggestions for the sustainable development of China’s CCUS-EOR industry, providing necessary decision-making references for CCUS policy-making departments.
