摘　　要：CO_(2)置换开采及封存的碳汇是降低我国南海水合物产业化开采成本的重要路径,不仅能保障粤港澳大湾区经济建设所需的能源供给,而且能降低大湾区过量的碳排放,与气态、液态CO_(2)相比,注入CO_(2)乳液置换效率更高。综述CO_(2)乳液在置换开采甲烷水合物中的应用,以及乳液的稳定性问题,讨论CO_(2)乳液开采南海水合物的优势及难点,并对下一步CO_(2)乳液法置换开采南海水合物进行分析,为未来天然气水合物开采及同步碳封存提供参考和建议。CO_(2) replacement mining and carbon sink sequestration is an important pathway to reduce the cost of industrial hydrate extraction in the South China Sea,not only to ensure the energy supply required for the economic construction of the Guangdong-Hong Kong-Macao Greater Bay Area,but also to reduce the excessive carbon emissions in the Greater Bay Area.Compared with gaseous and liquid CO_(2),the replacement efficiency of injected CO_(2) emulsion is higher.In this paper,the application of CO_(2) emulsion in the replacement of methane hydrate,and the stability of emulsion were summarized.The advantages and difficulties of CO_(2) emulsion in the exploitation of hydrate in the South China Sea were discussed,and the next step of CO_(2) emulsion replacement in the exploitation of hydrate in the South China Sea was analyzed.This work may provide reference and suggestions for future gas hydrate mining and simultaneous carbon sequestration.
