摘要: 随着温室效应的加剧,CO2地质储存已成为减缓全球气候变暖的有效方法之一. 可用于CO2 地下储存的场地主要有枯竭的油气田、深部咸水层和深部不可开采的煤层等,我国深部咸水层CO2地质储存潜力占总潜力的98%以上. 在全面分析CO2 地质储存适宜性影响因素的基础上,建立了适宜于沉积盆地深部咸水层CO2 地质储存的适宜性评价体系,主要包括地质安全性、储存规模、社会环境风险和经济适宜性4大指标层,共计28个评价指标,评价方法以层次分析法及指标叠加法为主. 以西宁盆地为研究实例,通过基于排除法的地质条件综合分析与层次分析法的定量评价相互验证,表明该指标体系和评价方法具有广泛的应用价值. 结果表明,西宁盆地一级构造单元中双树坳陷最适宜CO2地质储存,可作为CO2地质储存的优先选区.

Abstract: In this paper, on the basis of analysis of the factors affecting CO2 geological sequestration suitability, an index system which included four indicator levels was established. The evaluation index system, a total of 28 evaluation indexes, covers geological safety, storage scale, social and environmental risks and economic suitability. The evaluation method is based on AHP and index superposition method. Then Xining Basin was taken as a case study, and mutual authentication through comprehensive analysis of geological conditions and quantitative evaluation based on AHP was carried out. The results show that the suitability evaluation index system has wide application value and Shuangshu depression area has relatively good suitability of CO2 geological sequestration in Xining Basin.

Key words: CO2 geological sequestration, Xining Basin, evaluation index system, suitability evaluation
