天然气水合物（NGH）被视为未来的替代能源。目前，已在日本南海海槽和南海神狐海域进行了海洋沉积物水合物开采试验。水合物开采受沉积物中水气两相流动的影响，针对水合物聚集区海水储量巨大的特点，进行了水气两相流动分解水合物的实验研究。分析了海水气流量和初始水合物饱和度对甲烷水合物生成的影响。结果表明，海水气流有效地促进了水合物的分解，抑制了水合物的再生成。此外，随着海水流速的增加和气体流速的降低，热质传递速度加快，从而提高了MH的平均解离速率。此外，随着初始水合物饱和度的增加，流动通道的变化时间增加。此外，海水-气体流比去离子水-气体流更强地促进MH解离。
Natural gas hydrates (NGHs), regarded as an alternative future energy source. Currently, tests for hydrate exploitation from marine sediment have been performed in the Nankai Trough of Japan and the Shenhu area of the South China Sea. Hydrate exploitation is influenced by water-gas flow in the sediment, and considering the huge seawater reserves in hydrate accumulation areas, an experiment of seawater-gas flow was performed to dissociate hydrate. The effects of seawater-gas flow rates and initial hydrate saturation on methane hydrate (MH) production were analyzed. The results showed that seawater-gas flow efficiently promotes hydrate dissociation and inhibits hydrate reformation. Moreover, there was a faster heat and mass transfer with increasing seawater flow rates and decreasing gas flow rates, which enhanced the average MH dissociation rate. In addition, the variation time of the flow channel increased with higher initial hydrate saturation. Additionally, seawater-gas flow promotes MH dissociation stronger than deionized water-gas flow.
