In porous media containing gas hydrate, the hydrate morphology impacts the flow behavior of the fluid phases. We hypothesize that hydrate emplaces itself as a nonwetting phase and use this idea to describe relative permeability of water in a hydrate/water system. We perform steady‐state relative permeability measurements in hydrate‐bearing samples with a range of hydrate saturation. We measure and compare water relative permeability in the presence of gas and in the presence of hydrate and find that the water relative permeability is the same in both cases. This suggests that (1) relative permeability for hydrate systems can be obtained without performing difficult experiments on hydrate bearing sediments, (2) flow properties are porous‐media dependent, and (3) models that assume a fixed pore or tube geometry are inadequate.

水合物是多孔介质中的非润湿阶段

在含有气体水合物的多孔介质中，水合物的形态会影响液相的流动行为。我们假设水合物将其自身定位为非润湿相，并使用此思想来描述水在水合物/水系统中的相对渗透率。我们在水合物饱和度范围内的含水合物样品中进行稳态相对渗透率测量。我们测量并比较了在气体存在和水合物存在下的水相对渗透率，发现两种情况下水的相对渗透率都相同。这表明（1）无需对含水合物的沉积物进行困难的实验即可获得水合物系统的相对渗透率;（2）流动性取决于多孔介质，（3）假设固定孔或管的几何结构不充分的模型。
