英文摘要	Special experiments have been carried out to assess gas permeability variations associated with dissociation of pore hydrate in frozen sand samples at negative temperatures. The experiments were run on an originally designed system using frozen samples artificially saturated with methane hydrate which either remained stable or dissociated upon pressure drop. The measurements under different pressures and temperatures showed that the sand samples became more permeable to gas as pore hydrate dissociated at a pressure below equilibrium (0.1 MPa) and temperatures of -5 to -3 °C. The magnitude of the gas permeability increase varied depending on initial hydrate and ice saturation of the samples. © Academic Publishing House Geo. All rights reserved.
