Abstract
An in-situ hydraulic jet exploiting device and method of a low-permeability natural gas hydrate reservoir. The device includes a high-pressure reaction kettle configured for formation, fracturing and exploiting of a hydrate, a stable-pressure gas supply module configured to adjust and control a gas flow rate, a constant-speed constant-pressure liquid supply module configured to control a liquid flow rate or keep liquid injection pressure constant, a thermostatic water bath configured to provide a constant-temperature environment for a device system, a back-pressure module configured to automatically control an exploiting rate or exploiting pressure, an in-situ hydraulic jet permeability enhancement module, a data collection and processing module configured to collect and process basic system parameters, and a pipeline connecting various components.
