摘　　要：松辽盆地是中国主要的能源基地,随着中国振兴东北老工业基地政策的实施,如何应对工业和经济发展带来的CO_2排放量的增加,将成为亟需解决的问题。在盆地内进行CO_2地质储存将成为盆地内解决该问题的主要技术选择之一。以松辽盆地为研究对象,在深入分析松辽盆地CO_2地质储存条件的基础上,从储存规模、储存安全性和社会环境风险及经济适宜性4个方面综合考虑,构建了由16个指标组成的松辽盆地CO_2地质储存适宜性评价指标体系,利用灰色关联分析法对松辽盆地33个二级构造单元进行了盆地级适宜性评价工作,评价结果为进一步场地级目标靶区的筛选提供了科技支撑。Songliao Basin is one of China's major energy bases. With the implementation of the policy of revitalizing the old industrial bases in Northeast region, how to deal with the increase of CO_2 emissions arising from industrial and economic development has become an urgent problem. Performing CO_2 geological sequestration in this basin will be one of the major techniques to solve the problem. Therefore, with Songliao Basin as the study object and in consideration of the geological conditions of Songliao Basin, the authors selected indexes from the four aspects which include storage's size, storage's security, social environmental risk, economic suitability, and established an index system that includes 16 indicators by applying the gray relational analysis method to the basin level suitability assessment of the 33 Ⅱ tectonic units of Songliao Basin. The results provide a basis for target area selection of ground level.
