The invention discloses a heat-supply heating well overground structure. The heat-supply heating well overground structure comprises a low-temperature heating well and a high-temperature heating well,neutralization and exchange of cold water and hot water are realized between the parts, on the ground, of the low-temperature heating well and the high-temperature heating well through a ground equipment group, the sections of wellheads, located on the ground, of the low-temperature heating well and the high-temperature heating well sequentially comprise annuluses A, annuluses B and annuluses C from inside to outside, the ground equipment group comprises an annulus-B water pump arranged between the annulus B of the low-temperature heating well and the annulus B of the high-temperature heatingwell, channels between the annuluses B and the annulus-B water pump are annulus-B water pumping channels, and the annulus-B water pump further communicates with a normal-temperature water inlet through an annulus-B pump drain
