中文摘要：
应用混合物连续介质理论,考虑二氧化碳溶解建立了深部含水层二氧化碳运移的热流固耦合数学模型。利用该模型计算了深部含水层二氧化碳运移过程中二氧化碳饱和度、溶解质量分数和孔隙压力随时间的演化和扩散规律。计算结果表明：耦合作用下注入点处储层含气饱和度比非耦合作用下增加9.92%,二氧化碳质量分数减小4.85%,孔隙压力降低5.7%,二氧化碳在深部含水层运移过程中耦合效应十分明显。与传统渗流模型相比,本模型更接近于实际情况。
英文摘要：
Based on the continuum theory of mixture,considering the dissolution of carbon dioxide in deep aquifer,the thermo-hydro-mechanical coupling model for geological storage of carbon dioxide in deep aquifer is established.The dynamic change laws of carbon dioxide are calculated based on the proposed model.The calculating results are compared with the traditional seepage model.The examples show the coupling effect is very significant for geological storage of carbon dioxide in deep aquifer.Compared with the traditional model,the thermo-hydro-mechanical coupling model conforms to reality better.
