| description | The invention provides a geothermal exploitation construction method for collecting and communicating multiple wells to take heat in a water-resisting mode. The geothermal exploitation construction method is characterized in that a vertical well and a plurality of horizontal wells are in butt joint and communicate to take heat in the water-resisting mode, the vertical well serves as a water outlet heat taking well, the multiple horizontal wells are distributed on the periphery of the vertical well, and the horizontal wells serve as water injection wells. The method comprises the following steps of a, vertical well drilling construction; b, first horizontal well construction; and c, other horizontal well construction. The geothermal exploitation construction method has the advantages that the number of heat exchange channels is large, the heat exchange area is large, and sealing and isolating are safe and reliable; conventional geothermal resources can be provided for heating for cities or the peripheries of t |
