Abstract:In this paper, from the aspects of geothermal reservoir conditions, dynamic field, water chemistry and storage conditions, geological conditions of geothermal reinjection in Shanghe county have been studied. Combining with present condition of development and utilization of geothermal resources and technical conditions of the reinjection project, feasibility of geothermal tail water reinjection in Shanghe county has been studied. It is regarded that geothermal tail water reinjection can be gradually implemented under the existing conditions.
