摘要： The invention relates to a method for configuring a geothermal circulation system in a target underground region, comprising at least one injection wellbore (1) and at least one production wellbore (2), a hydraulic connection being created between the injection wellbore (1) and the production wellbore (2) via a crack system (4, 4′) in the target underground region, and a heat transfer medium being circulated via the injection wellbore (1), crack system (4, 4′), and production wellbore (2), comprising the steps of creating a plurality of cracks (4, 4′) in the target underground region by the incremental hydraulic separation of short wellbore sections and hydraulic crack generation starting from the respective separated wellbore section. The invention further relates to an arrangement for a geothermal circulation system in a target underground region, comprising at least one injection wellbore and at least one production wellbore, wherein a hydraulic connection is established in the target underground region between the injection wellbore and the production wellbore via a crack system, wherein the injection wellbore and the production wellbore in the target underground region have wellbore segments that are deflected at angles (α, β) of 0° to 80° to the horizontal line, and a plurality of cracks are provided for the hydraulic connection between the injection wellbore and production wellbore.
