摘　　要：盐水层CO_(2)封存是可行的技术部署方案之一,也是中长期CO_(2)深度减排的主要方式。针对盐水层封存潜力的评估要求,对CO_(2)地质封存的4种封存机理进行了系统阐述,并基于封存机理对沉积盆地中盐水层封存潜力的计算方法进行了梳理分析。通过总结归纳国内外盐水层封存评价体系,建立了涵括安全、技术、经济和社会环境4类评价指标层的盐水层封存适宜性评价指标体系,利用层次分析法确定了各指标的权重。对于具有开放构造和丰富水文地质作用的盐水层,推荐考虑残余气封存和溶解封存结合的方法评估封存潜力,盐水层CO_(2)地质封存适宜性评价指标体系的建立为开展全国性的CO_(2)封存适宜性评价工作提供参考。CO_(2)storage in saline aquifers is one of the feasible technical deployment schemes,and it is also the main approach to reduce CO_(2)emission in the medium and long term.To meet the assessment requirements of the storage potential in saline aquifers,four CO_(2)geological storage mechanisms are systematically expounded.Based on the storage mechanism,an evaluation index system for the suitability of CO_(2)geological storage in saline aquifers is established,including four evaluation index layers of safety,technology,economy,and social environment.The weight of each evaluation index factor is calculated using the analytic hierarchy process.For saline aquifers with an open structure and rich hydrogeology,it is recommended to consider the combination of residual trapping and solubility trapping to evaluate CO_(2)storage potential.The CO_(2)geological storage suitability evaluation index system of saline aquifers provides a reference for conducting the national CO_(2)storage suitability evaluation.
