Thermal conductivity of 4-component artificial methane hydrate sediment was measured with newly developed equipment during dissociation process induced by depressurization. With dissociation of methane hydrate in the pore space, thermal conductivity of the sample sediment decreased. On the other hand, the thermal conductivity increased as the methane hydrate saturation increased. Estimation of the thermal conductivity of the sample was also carried out with some thermal conductivity mixing models. The distribution model reproduced measured values appropriately when hydrate saturation was small. In contrast, the values calculated from parallel model relatively coincided with measured values when hydrate saturation was high.
