摘　　要：玄武岩分布广泛,CO_(2)埋存潜力巨大,为掌握玄武岩CO_(2)矿物封存的研究现状,推动我国玄武岩CO_(2)地质埋存技术发展,综述了玄武岩的储层物性、CO_(2)封存机理、埋存潜力、埋存方案等方面的研究进展及工程实施效果,总结了CO_(2)玄武岩埋存优势及亟待解决的关键问题。气水同注可以实现最快的CO_(2)矿物封存,冰岛的碳封存项目CarbFix已成功证明了在玄武岩开展CO_(2)矿物封存的可行性,但仍存在以下关键问题需解决,包括揭示地层孔隙条件下CO_(2)-玄武岩-地层水的相互作用特征,明确地化反应导致的固相颗粒运移、沉积以及可能引起的孔喉堵塞风险,建立完善的玄武岩储层筛选和CO_(2)埋存潜力评价方法,提出成本低、安全有效的CO_(2)快速矿物封存方案。Basalts are widely distributed with great CO_(2) storage potential.In order to review the current research status of CO_(2) mineral trapping in basalts and promote CO_(2) geological storage technology in China,research of physical properties of basalts,CO_(2) trapping mechanism,storage potential and storage scheme were reviewed,and the advantages of CO_(2) storage in basalts and key issues were summarized.The fastest CO_(2) mineral storage can be achieved when CO_(2) is dissolved in water and injected,and the CarbFix project in Iceland successfully proved the feasibility of CO_(2) mineral storage in basalts.However,the following key issues need to be solved,which includes revealing the interaction characteristics of CO_(2)-basalt-formation water under formation pore conditions,clarifying the migration and deposition of solid particles and the possible risk of pore throat blockage caused by chemical reactions,establishing a complete method of basalt reservoir screening and CO_(2) storage potential evaluation,and proposing a low-cost,safe and effective CO_(2) rapid mineral storage scheme.
