中文摘要	the gas production behavior from methane hydrate in porous sediment by injecting the brine with the salinity of 0−24 wt % and the temperature of −1 to 130 °c was investigated in a one-dimensional experimental apparatus. the results show that the gas production process consists of three periods: the free gas production, the hydrate dissociation, and the general gas reservoir production. the hydrate dissociation accompanies the temperature decrease with the injection of the brine (nacl solution), and the dissociation duration is shortened with the increase of the salinity. with the injection of hot brine, instantaneous hydrate dissociation rate also increases with the increase of the salinity. however, while the nacl concentration is beyond a certain value, the rate has no longer continued increasing. thermal efficiency and energy ratio for the hydrate production can be enhanced by injecting hot brine, and the enhanced effectiveness is quite good with the injection of high salinity at lower temperature.
