摘　　要：为了分析二氧化碳置换甲烷开采海底天然气水合物的经济性开采方式和条件,利用Sloan等人的气液系统气体水合物生成驱动力公式,结合海水中二氧化碳和甲烷水合物的相平衡条件理论预测结果和南海冬季实际水文条件,定量研究了用摩尔吉布斯自由能变表示的二氧化碳和甲烷气体水合物生成/分解驱动力。In order to analyze the carbon dioxide gas hydrate methane replacement to exploit marine economy and mining conditions,gas-liquid system gas hydrate Sloan are used to generate driving force formula,combined with carbon dioxide.Methane hydrate in the water phase equilibrium conditions and actual hydrological conditions of South China Sea in winter are studied as well as the quantitative study of carbon dioxide and methane gas hydrate formation/change represented by the molar Gibbs free decomposition of driving force.
