摘　　要：随着CO2地质储存、废液的深部埋存、地热资源以及深层卤水资源开发等研究进展,深部水文地质条件分析受到不断重视,其中深部含水层结构的构建与刻画是深部水文地质条件分析的基础。针对鄂尔多斯盆地CO2深部咸水层储存,基于地质资料、钻孔数据和沉积相特征,利用GMS软件及其中的MODFLOW模块构建了深部水文地质结构模型,很好地显示了研究区关键储盖层的空间展布,可为CO2深部咸水层储存容量评价、场地选择以及工程安全性评价等提供基础。With the research development on the CO2 geological storage,liquid-waste injection disposal in deep formation,geothermal resources and deep brine resources,the analysis of deep hydrogeological condition has contracted more attention.The deep hydrogeological structure model building is the basis of deep hydrogeological analysis.Coupling geological data,drilling data and characteristics of sedimentary facies,the deep hydrogeological model of Ordos Basin has been built by GMS software and its MODFLOW package for CO2 geological storage in deep saline aquifers.Spatial distribution of key reservoir and caprock can be well displayed in this three dimensional model which can provide the basis of CO2 geological storage capacity in deep saline aquifers,site selection and engineering safety evaluation.
