摘　　要：二氧化碳地质封存联合深部咸水开采技术(CO_(2)-EWR)被认为是有效的碳减排途径之一。在新疆准东地区率先开展CO_(2)-EWR技术,可在实现CO_(2)减排的同时获得咸水,在一定程度上缓解当地的水资源短缺问题,取得环境经济双重效益。以往研究大多以概化模型为主,缺乏工程实践依托,根据准噶尔盆地东部CO_(2)源汇匹配适宜性评价结果,基于我国首个CO_(2)-EWR野外先导性工程试验场地资料,构建拟选CO_(2)-EWR场地西山窑组三维(3D)非均质模型开展了场地尺度CO_(2)-EWR技术潜力研究。研究表明,拟选场地CO_(2)理论封存量为1.72×10^(6)(P50)t,动态封存量为2.14×10^(6) t。采用CO_(2)-EWR技术可实现CO_(2)动态封存量11.18×10^(6) t,较单独CO_(2)地质封存提升5.22倍,同时可增采咸水资源10.17×10^(6) t,CO_(2)采水比率为1∶0.91。同时,该技术可有效缓解因CO_(2)大量注入引起的储层压力累积,提高CO_(2)封存效率,增加咸水开采潜力。本研究可为新疆准东地区实施规模化CO_(2)地质封存联合深部咸水开采工程提供理论依据和技术支撑。CO_(2) geological storage combined with saline recovery(CO_(2)-EWR)is considered to be one of the effective storage methods.Taking the lead in carrying out CO_(2)-EWR technology in the eastern Junggar of Xinjiang can achieve CO_(2) emission reduction and mean while produce saline water,which can alleviate the local water resources shortage problem to a certain extent,and obtain dual benefits of environment and economy.Previous research mainly focused on generalized models,and the support of engineering practices is lacking.Based on the evaluation results of the suitability of CO_(2) source-sink matching in the eastern Junggar Basin and the geological data of the first CO_(2)-EWR field pilot test site in China,a 3D heterogeneous model of the Xishanyao Formation of the CO_(2)-EWR test site in the eastern Junggar Basin is constructed to study the potential of the CO_(2)-EWR technology.The results show that the the oretical storage capacity of CO_(2) at the test site is 1.72×10^(6)(P50)tons,and the dynamic storage capacity is 2.14×10^(6) tons.When the CO_(2)-EWR technology is adopted,the CO_(2) dynamic storage capacity can reach 11.18×10^(6) tons,which is 5.22 times the CO_(2) geological storage only,and may increase the production of the saline water resources by 10.17×10^(6) tons with a mass ratio of 1 to 0.91 of CO_(2) sweeping out saline water.Meanwhile,the CO_(2)-EWR technology can effectively slow down the accumulation of reservoir pressure caused by the massive injection of CO_(2),improve the efficiency of CO_(2) storage,and increase the saline water production potential.This study can provide theoretical basis and technical support for the implementation of large-scale CO_(2) geological storage combined with deep saline water production project in the eastern Junggar of Xinjiang.
