摘　　要：CO_(2)的人为排放严重威胁人类的生存环境,导致生态系统发生重大变化。近年来提出的地质封存是处理大气中多余CO_(2)的技术之一,根据机制可分为物理封存和化学封存,前者依赖储层岩石孔隙的物理特性,后者则通过CO_(2)与地层岩石的反应实现。化学方法中的矿化封存是利用CO_(2)转化为稳定固体碳酸盐,达到长期储存的目标,被视为最安全稳定的封存技术。通过探讨CO_(2)矿化封存的机理及其潜力,对比分析了不同岩石中的反应机制、影响因素和矿化速率、储存能力,总结了玄武岩和砂岩中CO_(2)矿化封存的优缺点,结合目前全球已经成功实施的2例玄武岩矿化封存示范工程,提出碎屑岩储层中CO_(2)矿化封存思路和展望。Anthropogenic emissions of CO_(2)pose a serious threat to the human living environment and lead to significant changes in the ecosystem.Geological storage,which has been proposed in recent years as one of the technologies to deal with excess CO_(2)in the atmosphere,can be categorized into physical storage,which relies on the physical properties of the pores of the reservoir rock,and chemical storage,which is realized through the reaction of CO_(2)with the surrounding rocks.The chemical method of mineralized storage utilizes the process of converting CO_(2)into stable solid carbonates to achieve the goal of long-term storage,which is regarded as the safest and most stable storage technology.By discussing the principle and potential of CO_(2)mineralization,we comparatively analyzed the reaction mechanisms,influencing factors,mineralization rates,and storage capacities in different rocks,and summarized the advantages and disadvantages of CO_(2)mineralization in basalt and sandstone.Combined with two basalt mineralization demonstration projects that have been successfully implemented globally at present,we put forward the ideas and prospects for CO_(2)mineralization and storage in clastic rock reservoirs.
