Claim 9:
10. A method for, using the device of claim 1 and the reactor, wherein the reactor comprises the upper cover, the reactor body, and the lower cover, and the method comprises:
sealing a predetermined number of the perforations or providing each of the predetermined number of the perforations with the sand control unit;
sealingly disposing the well inside the reactor throughout a horizontal direction or a vertical direction and initiating the hydrate formation process, wherein the upper end of the well protrudes from the upper cover of the reactor, the perforations are positioned inside the reactor body, and the lower end of the well protrudes from the lower cover of the reactor; and
after the natural gas hydrates are formed in the reactor, allowing the gas-water-sand mixture to enter the well through the perforations, discharging the gas-water-sand mixture through the exploitation passage, discharging the water through the water discharging passage, and discharging the methane gas through the gas discharging passage.
