This article investigates the temperature distribution and flowing characteristics of the dissociated gas and water from hydrate in porous sediment by utilizing a one-dimensional experimental model setup. With the developed apparatus, the experiments have been run for the thermal stimulation method by injecting hot water with different temperatures and rates. The experimental result suggested that the gas production rate increases with time until it reaches a maximum, and then it begins to decrease. However, the water production rate keeps nearly constant during the whole production process. The injection water temperature and rate, as well as the hydrate content in the sediment, all influence the energy ratio of thermal stimulation production.
