| Abstract: | In mitigating the trend of global warming,CO2 geological sequestration becomes one of the effective methods for reducing the amount of CO2 emissions to the atmosphere.Regional suitability assessment constitutes the basis of selecting CO2 geological sequestration target areas.Both selecting suitable evaluation indicators and determining the weights have important effects on the reasonableness of the evaluation results.Considering the geological conditions of Songliao Basin and taking six Ⅰ tectonic units as the evaluation objects,the research established an index system which included 4 aspects,20 indicators and 5 indicator levels.The 4 aspects covered the scale of geological sequestration,the economy of geological sequestration,the conditions of geological sequestration and the security of geological sequestration.Using AHP(Analysis Hierarchy Process) to determine the indicator weights,and considering the fuzziness of grading standards,the authors obtained a fuzzy synthetic evaluation method of CO2 geological sequestration based on AHP.The research applied this method to the suitability evaluation of the 6 Ⅰ tectonic units and obtained the CO2 geological sequestration suitability.The results of the evaluation show that the central depression area has relatively good suitability of CO2 geological sequestration,which can hence be used as the CO2 geological sequestration priority area.It is shown that the northern plunging area,western slope area,and southeast uplift have general suitability for CO2 geological sequestration,whereas the northeast uplift area and southwest uplift area are not suitable for the geological sequestration of CO2. |
