Method for rapidly calculating geothermal resources of sedimentary basin through multi-data fusion

The invention discloses a method for rapidly calculating geothermal resources of a sedimentary basin through multi-data fusion, and the method comprises the following steps: S1, building a three-dimensional geologic model of a heat reservoir structure of the sedimentary basin through the equal-thickness maps of different stratums and heat reservoirs of the sedimentary basin, and determining the burial depths of different heat reservoirs and the spatial distribution states of the different heat reservoirs; s2, a one-dimensional steady-state heat conduction method is utilized to calculate and obtain temperature distribution diagrams of different heat reservoirs; s3, utilizing a volumetric method to calculate and obtain geothermal resource intensity distribution diagrams of different heat reservoirs; and S4, converting the geothermal resource intensity into geothermal resource quantity by utilizing an integral method. According to the method, geothermal parameters of different thermal storage point positions can
