The invention discloses a natural gas well head heating system comprising a condenser, a working medium compressor and a working medium heating device connected in cycle; the condenser is arranged ona high pressure gas well head, and the high pressure natural gas is heated and conveyed to a gathering and transport network via the condenser; partial the high pressure natural gas extracted from thehigh pressure gas well head enters the working medium compressor, and pressure of a heat pump working medium boosts, thus driving the heat pump working medium to circulate within the condenser, the working medium compressor and the working medium heating device. The advantages are that the system can use the high pressure natural gas pressure to drive the working medium compressor to circulate and heat up the high pressure natural gas extracted from the high pressure gas well head, thus saving energy consumption, and reducing the pollution degrees.
