摘要
碳捕集、利用与封存(CCUS)技术是降低二氧化碳(CO2)排放、缓解气候变化问题的重要措施.作为CCUS技术的重要组成部分,CO2地质封存是我国能源工业领域实现碳中和目标的"兜底"技术.常见的CO2封存地质体包括深部咸水层、枯竭油气藏、深部不可采煤层和玄武岩等,不同地质体中CO2的封存过程及其机理存在差异.综述了不同地质体中的CO2封存机理、国际国内CO2封存的主要工程实例以及不同地质体中CO2封存潜力的计算方法,并对CO2地质封存的前景进行了展望.
Abstract
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.
