气候变化背景下二氧化碳地质封存的盆地级选址评价方法
Assessment Methodology of Basin-Scale Site Selection for CO2 Geological Storage under Background of Climate Change

本文首先回顾了二氧化碳封存的盆地级选址评价方法，重点介绍Bachu提出的一种单级指标评价的盆地级选址评价方法，此方法能够对多个盆地或盆地的不同区域进行评价、排序和筛选。在设计实现快速计算表格的同时，对Bachu方法指标敏感性进行了评估。利用该方法对鄂尔多斯盆地进行评价，评价结果为0.81，表明鄂尔多斯盆地是一个适宜的CO2地质封存场地。对该方法的指标进行敏感性分析表明，地热条件、盆地位置、地质特征和水文地质特征对评价结果的影响最大。同时，利用基于层次分析法的模糊综合评价法对鄂尔多斯盆地进行比较评价，得出其场地等级为良，证明Bachu评价方法在鄂尔多斯盆地是有效的，其结果是合理的，两种方法相互证实了鄂尔多斯盆地作为CO2地质封存场地的可行性。将两种方法进行对比，Bachu的方法操作简单、计算速度快，能够实现多个盆地或盆地的不同区域进行评价、排序和筛选。

Abstract: An assessment method of basin-scale site selection with a set of 15 criteria is introduced for the screening and ranking of sedimentary basins in terms of their suitability for CO2 geological storage. The application is given for Ordos Basin, and its total score is 0.81, which shows its suitability for CO2 geological storage. According to the sensitivity analysis, criteria, geothermy, location, geology and hydrogeology have the greatest influence on the total score of the basin. An application of AHP (Analytic Hierarchy Process)-fuzzy comprehensive method is also conducted on the assessment of Ordos Basin. Its results prove Bachu’s assessment method, and confirm that Ordos Basin is suitable for CO2 geological storage. Compared to the AHP-fuzzy comprehensive assessment method, the screening and ranking method developed by Bachu is easier to operate, and has a wider application for the assessment, screening and ranking of basins and areas.
