description The invention relates to the technical field of geothermal energy development, in particular to a fracturing and guiding process for a geothermal well, which comprises the following steps of: A, injecting cement into an annular space between a casing and a well wall of the geothermal well for well cementation after the casing is placed in the geothermal well; B, performing sectional perforation onthe high-temperature section of the geothermal well after the cement is solidified, and ejecting through holes on different heights of the high-temperature section of the geothermal well; C, performing hydraulic fracturing on the through holes by adopting a fracturing system after perforation, fracturing a rock layer at the through holes corresponding to the high-temperature section of the geothermal well to generate cracks, continuously injecting filling liquid with a heat-conducting proppant into the cracks, and filling the crack space with the filling liquid extending forwards; D, after the cracking is finished, m
