Abstract
A device and a method for gas-water-sand separation and measurement during a simulated exploitation of natural gas hydrates are disclosed. The device includes a natural gas hydrate formation and dissociation system and a filtering unit. The natural gas hydrate formation and dissociation system includes a compressed air pump, a reactor, and a water-bath temperature regulating unit. The filtering unit includes a kettle body, wherein an inlet end of the kettle body is connected to the sand-control liner zone, an outlet end of the kettle body is connected to a water-collecting container, and a plurality of filtering layers are disposed inside the kettle body from the inlet end to the outlet end. The method is conducted using the device. The device and the method realize the gas-water-sand separation and measurement of produced gas-water-sand mixture during a simulative exploitation process, allowing for a direct inspection on a sand production and sand control.
