Embodiment Construction
[0035] Figure 1~2 It is the best embodiment of the natural gas hydrate drainage gas production device and its mining method of the present invention, below in conjunction with the attached Figure 1~2 The present invention will be further described.
[0036] Refer to attached figure 1 : The natural gas hydrate drainage and gas production device includes a natural gas hydrate production well 3 connected to the natural gas hydrate layer 29, an electric submersible pump 4 fixed at the bottom of the natural gas hydrate production well 3 and a gas hydrate production well 3 fixed in the middle The microwave generator 14 is connected to the gas-liquid separator 7 in the well above the electric submersible pump 4. The microwave generator 14 heats the natural gas hydrate layer 29, and the gas and water generated by the decomposition of the natural gas hydrate are separated by the gas-liquid separator 7 in the well. The gas is transported to the ground through the gas production casi...
