摘　　要：在当前碳达峰、碳中和背景下,CO_(2)地质储存被认为是降碳减排、减缓温室效应最直接、最有效的办法。笔者聚焦江西省CO_(2)减排需求,以江西省内发育的9个重点中新生代沉积盆地为研究对象。采用碳封存领导人论坛(CSLF)提出的方法,计算得出江西省中新生代沉积盆地CO_(2)有效储存量为18226.3×10^(6) t,束缚气储存机理有效储存量为16869×10^(6) t,溶解气储存机理有效储存量为1357.3×10^(6) t。构建了以地质安全性、储存规模、社会经济性为核心,涵盖19项评价指标的CO_(2)地质储存潜力适宜性综合评价指标体系,并引入变异系数法–综合评价模型,客观地评价江西省中新生代CO_(2)地质储存潜力及其适宜性。评价结果显示,江西省CO_(2)地质储存适宜性优先顺序分别为:鄱阳盆地、清江盆地、信江盆地、抚州盆地、赣州盆地、锦江盆地、吉泰盆地、版石盆地和会昌盆地。其中,鄱阳盆地、清江盆地储存潜力分别达到适宜、较适宜等级。Under the current background of carbon peaking and carbon neutrality,carbon dioxide geological storage is considered to be the most direct and effective way to reduce carbon emissions and mitigate the greenhouse effect.This paper focuses on the carbon dioxide emission reduction demand of Jiangxi Province,and takes 9 key Mesozoic and Cenozoic sedimentary basin developed in Jiangxi Province as the research object.Adopting the approach proposed by the Carbon Storage Leadership Forum(CSLF),it is calculated that the effective storage of carbon dioxide in the Mesozoic Cenozoic sedimentary basin in Jiangxi Province is 18226.3×10^(6) t;the effective storage capacity of the bound gas storage mechanism is 16869×10^(6) t;the effective storage capacity of dissolved gas storage mechanism is 1357.3×10^(6) t.It has established a comprehensive evaluation index system for the suitability of carbon dioxide geological storage potential,with geological safety,storage scale,and socio-economic benefits as the core,covering 19 evaluation indicators,And introduce the coefficient of variation method-comprehensive evaluation model to objectively evaluate the geological storage potential and suitability of CO_(2)in the Mesozoic and Cenozoic in Jiangxi Province.The evaluation results show that the priority order of CO_(2)geological storage suitability in Jiangxi Province is as follows:Poyang basin,Qingjiang basin,Xinjiang basin,Fuzhou basin,Ganzhou basin,Jinjiang basin,Jitai basin,Banshi basin,and Huichang basin.Among them,the storage potential of Poyang basin and Qingjiang basin has reached suitable and relatively suitable levels,respectively.
