  Based on the principle of hydrates decomposition and Darcy’s Law of fluid flow in ocean sediments, a model for natural gas production from hydrate deposits in deep-sea by depressurization is presented in this paper. Meanwhile, the pressure governing equations and the formula of output of gas are obtained.

  根据天然气水合物在地层中的分解渗流规律,建立了利用降压法对水合物进行开采的物理模型,并由达西定律推导了其压力控制方程以及天然气的产量计算公式。
