The hot spot in the research of the gas hydrate is the marine gas hydrate exploration method today. We put forward the hydraulic lifting method as a new model to exploit submarine gas hydrates through the analysis of the gas hydrate reservoiring mechanism in the South China Sea. We introduced the composition and working principle of hydraulic lifting system,proposed the related parameters of the equipment. Meanwhile,the gas production and energy efficiency of the method were simply evaluated. The calculation result of the method showed that the new model has the advantages of high gas production with high efficiency. It is feasible to exploit gas hydrates in the South China Sea by using this method. Hydraulic lifting method of mining gas hydrates overcomes the technical difficulties of other traditional mining method and provides a new way of thinking and technical foundation for marine gas hydrate exploration.
