Abstract
The geothermal waters found in various geological formations may differ. They can supply freshwater, brackish water, saline water, and brine with mineral concentrations surpassing 30 g/dm3. Cooling water in a geothermal system can cause the precipitation of solid phases, which then enter an injection well, significantly affecting its injectivity. Much of Poland's geothermal water is characterized by high mineralization of up to 150 g/dm3 and even higher, which raises real problems and limitations in the geothermal system's operation. The paper presents the results of a study investigating the effects of different temperatures on the precipitation of solid, secondary deposits phases from geothermal water. The alteration of permeability in the near-well zone during injection was analyzed under varying temperature circumstances, while assuming the replication of reservoir conditions. The results can enhance the optimization of the geothermal plant's operating parameters. To estimate the temperature to which it is advisable to cool the geothermal fluid, mathematical models defining the operating conditions of geothermal systems were used.
