不同地质体中CO2封存研究进展OACSTPCD

Carbon capture,utilization and storage(CCUS)technology is an important measure to reduce carbon dioxide(CO2)emissions and mitigate climate change issues.As an important component of CCUS technology,CO2 geological storage is the"bottom line"technology for achieving carbon neutrality goals in China's energy industry.Common geological formations for CO2 storage include deep brine aquifers,depleted oil and gas reservoirs,deep unminable coal seams,and basalt formations.The processes and mechanisms of CO2 storage in different geological formations are different.The CO2 storage mechanisms in different geological formations,the main engineering examples of CO2 storage at home and abroad,and the calculation methods of CO2 storage potential in different geological formations were summarized.The prospects for CO2 geological storage were discussed.
