摘　　要：针对海洋渗漏型天然气水合物含量高、成藏浅、产出集中的特点，结合深海开采金属锰结核的方法。提出了一种全新的水合物开采模式，即用水力法提升水舍物。同时对该种方法的能量效率和产量进行了简单的评估。模型计算表明，该种开采方法具有产量大、能耗低的优点，在提升海底1000m的水合物时，即使水合物含量低至20％，其能量效率仍可高达60，远远高于注热开采的7-12的能量效率。Due to the features of high concentration, shallow buried depth of offshore leakage gas hydrate reservoir, a new production method of gas from hydrate has been provided, based on the production of manganese nodes from deep sea, i.e. the hydraulic lifting of gas hydrate. At the same time, the output and energy ratio of this method have been evaluated. The calculation results of the method suggested that this new production model has the advantages of high output with low energy consumption. For hydrate under 1000m depth, the energy ratio can reach 60 with even 20% concentration of hydrate in lifting material, which is much higher than the energy ratio of gas production from hydrate by thermal stimulation.
