2-04　MHを胚胎した薄型ガラス多孔質モデルの浸透率測定

抄録

In this study, we developed an in situ chamber to measure water permeability as a function of the methane hydrate (MH) habit in pore space using a two-dimensional glass micromodel. We simultaneously observed MH crystallization behavior and measured the water permeability of the porous media. We compared our results with various water permeability models of MH sediments and found that the nonempirical relative permeability (NRP) models showed relatively good agreement.
