Abstract
A device for simulating exploitation of a natural gas hydrate in a permeable boundary layer includes a high pressure reaction kettle, a formation simulation unit and an aquifer maintaining unit. A water bath jacket externally connected with constant temperature water bath is arranged on the outer wall of the high pressure reaction kettle for providing a necessary temperature condition for the high pressure reaction kettle. A simulative well at the center of the top of the high pressure reaction kettle is connected with liquid injection, gas injection, gas production and water production equipment. An aquifer interface at the bottom of the high pressure reaction kettle is connected to the aquifer maintaining unit through a pipeline. The simulation device simulates the geological environment of a hydrate reservoir, allowing comprehensive evaluation of hydrate exploitation under different formation permeability and different formation pressure gradients.
