摘　　要：埋存二氧化碳法置换天然气水合物在开发水合物新能源、降低二氧化碳排放方面具有独特优势,因此该方向成为二氧化碳埋存、天然气水合物开采方向的重要研究内容之一。在前人基础上,本文综述了埋存二氧化碳法置换天然气水合物在工程概念模式及实验模拟方面所取得最新进展。指出可以以南海北部陆坡、青海冻土水合物为目标,开展针对性研究,重点针对提高二氧化碳置换效率与风险评估问题等进行研究。Storage CO2 in gas hydrate formation to recover natural gas is one of important research content in both gas hydrate and CO2 Storage fields because the method takes the advantage of combining the exploitation of new energy of gas hydrate with the storage of CO2.In this paper,the latest development of engineer conceptual model and the experimental simulation of storage CO2 in gas hydrate formation to recover natural gas are reviewed.Based on the review we consider that the regions of bearing natural gas hydrate in north slope of the South China Sea and Qinghai permafrost should be used as research targets to carry out the storage CO2 in gas hydrate formation to recover natural gas.The main research effort should focus on the replacement efficiency of CO2 and risk assessment.
