摘  要:海洋二氧化碳捕集、利用与封存(CCUS)是应对全球气候变化、减排温室气体CO_(2)的关键技术之一,也是实现中国碳中和目标愿景解决方案的重要组成部分。中国近海沉积盆地封存潜力巨大,2022年中国首个CO_(2)海底地质封存示范工程已在南海珠江口盆地咸水层中正式启动。日本苫小牧咸水层封存项目作为迄今为止亚洲最成功的海底封存项目,其CO_(2)封存监测工作为我国离岸封存项目的开展提供了重要的实践参考及技术指导。文章全面回顾了苫小牧CCS项目案例情况,对项目执行、场地监测内容及布点、监测设施及技术、监测结果等进行分析,总结苫小牧CCS项目的成功经验,以及陆—井—海结合一体化的多层次、全方位的监测体系,旨在助力中国海上CO_(2)封存项目顺利运行,确保海洋生态环境安全。Offshore carbon dioxide(CO_(2))capture and storage(CCS)is one of key technologies to cope with global climate change and reduce greenhouse gases such as CO_(2),and also an important solution to achieve carbon neutrality goal of China.Offshore sedimentary basins of China have huge storage potential,and the first offshore CO_(2)geological storage demonstration project has been officially launched in the Pearl River Mouth Basin of the South China Sea in 2022.Japan’s Tomakomai CCS project is the most successful offshore CO_(2)geological storage project in Asia so far,and its monitoring work provides important practical references and technical experiences for the development of China offshore CCS projects.Based on this consideration,this paper comprehensively reviews the case of Tomakomai CCS project,analyzes its implementation,site monitoring items and distribution,monitoring facilities and technologies,monitoring results,etc.,summarizes the successful experience of the Tomakomai CCS project and the multi-level and all-round monitoring system of land-wellbore-marine integration,aiming to help offshore CCS projects of China run smoothly,and to ensure the security and safety of the marine ecological environment.
