Challenges and countermeasures for CCUS-EOR development in China's oil and gas industry
Carbon dioxide capture,utilization and storage(CCUS)is the underpinning technology to achieve the goals of carbon peaking and carbon neutrality,and has a broad development prospect.Among the various aspects of CCUS,CO2 capture and storage,and enhanced oil recovery(EOR)are important means of CO2 utilization and storage.Through preliminary research,the whole process technology system of CCUS-EOR in the oil and gas industry has matured.CO2-EOR is an important means to enhance recovery in low permeability reservoirs,and management innovation is the key to promoting the realization of the effect of CCUS-EOR projects.At present,there are still challenges in the development of CCUS-EOR such as uncertainty of CO2 sources and high prices constrain the realization of project benefits,different basins still need in-depth research on the mechanism of oil repulsion,the costs of applying carbon capture,pipeline transmission,oil displacement,and other auxiliary technologies are relatively high,and the adaptability of ground engineering faces a big challenge.It is recommended to further improve the criteria of CO2-EOR evaluation and selection to reduce the investment risk,accelerate the construction of systematic and low-cost CCUS-EOR technology system,further improve the top-level design and build internal and external cooperation mechanism to form the synergy of business development,actively strive for the support of low-carbon industrial policies to ensure the healthy development of CCUS-EOR business,do a good job in the construction of key basins'comprehensive energy bases to build national-level low-carbon&carbon-negative demonstration areas,and accelerate the formation of CCUS integrated economic evaluation methods.
