摘要
煤层CO_(2)地质封存作为CO_(2)捕集、利用与封存的重要组成部分,对我国“双碳”目标与矿山绿色低碳转型具有重大的战略意义。本文通过文献调研、比较分析和理论框架构建等方法,论述了煤层CO_(2)地质封存技术的主要分类、原理及特点,总结提出了煤层CO_(2)封存选址的流程指标及评价体系,可视化展示了煤层CO_(2)封存的理论选址模型,旨在为煤层CO_(2)地质封存示范工程建设和规模化应用提供理论依据。煤层CO_(2)地质封存技术中,在大尺度地质特征与经济特征筛选目标靶区基础上,可采用模糊综合评价法从局域地质调查、社会环境和成本收益3个方面筛选评估封存场地。筛选评估过程中应加强各种地质调查技术的综合应用和进行有效的CO_(2)封存潜力评价。
As an important part of CO_(2) capture,utilization and storage,CO_(2) geological storage in coal seams is of great strategic significance to China’s“double carbon”goal and green low-carbon transformation of mines.Through literature research,comparative analysis and theoretical framework construction,this paper discusses the main classification,principle and characteristics of coal seam CO_(2) geological storage technology,summarizes and puts forward the process index and evaluation system of coal seam CO_(2) storage site selection,and visually displays the theoretical site selection model of coal seam CO_(2) storage,aiming to provide theoretical basis for the construction and large-scale application of coal seam CO_(2) geological storage demonstration project.In the CO_(2) geological storage technology of coal seam,on the basis of screening target areas with large-scale geological and economic characteristics,the fuzzy comprehensive evaluation method can be used to screen and evaluate the storage sites from three aspects:local geological survey,social environment and cost-benefit.In the process of screening and evaluation,the comprehensive application of various geological survey techniques should be strengthened and the effective evaluation of CO_(2) storage potential should be carried out.
