摘要： The invention provides an efficient gas hydrate production system using flue gas waste heat/solar absorption heat pump to compensate reservoir heat, includes a heat source absorption system, heat pump heating system and reservoir heat compensation system and realizes efficient exploitation of submarine natural gas hydrate in the way of heat compensation. The invention uses the low-grade heat energy of offshore platform to solve the problems of heat source and energy consumption in the process of natural gas hydrate exploitation by. It provides a commercial feasible scheme for large-scale exploitation of natural gas hydrate. The condenser module, evaporator module and injection well module of the invention can be flexibly increased or decreased, and can adapt to a variety of actual hydrate reservoir distribution; the injection well module adopts ball-nozzle, which can disperse and evenly inject the hot injected water into the reservoir.
