Method, pipe column structure and system for developing hot dry rock geothermal resources

The invention provides a method, a pipe column structure and a system for developing hot dry rock geothermal resources. The method comprises the steps that S10, the well position of an injection well is determined, and the injection well is drilled out; s20, layer section division and staged fracturing transformation are conducted on the injection well, and the space distribution state of cracks is obtained; s30, according to the spatial distribution state of the cracks, the well position of a production well is determined, and the production well is drilled out; s40, segmented well completion pipe columns are put into the injection well and the production well correspondingly; and S50, carrying out production testing, determining production development parameters according to the obtained production testing data, and carrying out development. Based on the technical scheme, the utilization effect of the hot dry rock is improved through staged fracturing, staged injection and staged production, the sweep degre
