Heat supply device integrating waste oil well circulation heat extraction and two-stage heat pump

The utility model discloses a heating device integrating waste oil well circulation heat extraction and a two-stage heat pump. The heating device comprises an alpine region flat plate collector, a low-temperature air heat source pump, a high-temperature source heat pump unit, a layered buffer water tank, a shallow cluster heat exchange system and a house building. And a secondary source heat system is mounted in the high-temperature source heat pump unit. According to the utility model, a method that a shallow cluster well heat exchange system is used as a main heat source is adopted, the temperature of the shallow cluster well is exchanged through the heat exchange system, and the pipeline is connected with the shallow cluster well heat exchange system and the layered heat storage buffer water tank in the skid-mounted heat preservation combined container; the low-temperature air source heat pump unit in the box, the flat plate collector in the alpine region, the high-temperature water source heat pump unit a
