Abstract The permeability of porous media is one of the critical parameters that determines gas recovery from natural gas hydrate reservoirs. We measured the permeability of quartz sands by injecting water at a certain flow rate. In hydrate-bearing sands, the larger the hydrate saturation, the smaller the shape factor in the presence of hydrate. A kr - SH relationship with the hydrate saturation both lower and higher than 10% was obtained. Based on the experimental results, the saturation exponent n varied from 6.0 to 1.0.

含甲烷水合物的石英砂渗透率测量

摘要 多孔介质渗透率是决定天然气水合物储层采气率的关键参数之一。我们通过以一定流量注入水来测量石英砂的渗透率。在含水合物砂岩中，水合物饱和度越大，存在水合物时的形状因子越小。获得了水合物饱和度低于和高于 10% 的 kr - SH 关系。根据实验结果，饱和指数 n 从 6.0 变化到 1.0。
