Abstract

In order to study the effects of temperature reducing ratios on the configuration and properties of methane hydrate formation inside non-saturated coarse sand and loess,two reducing temperature methods,12℃→0.5℃/3h and 12℃→0.5℃/50h,were used.It was experimentally shown that the changes of temperature reducing ratios caused no effects on the final configuration of methane hydrate formation and slow temperature reducing was favorable for the convergent formation of methane hydrate inside media,under which the hydrate formation scopes inside media were larger.
