摘要：Attaining the proper values of main production parameters of
operating geothermal installation: outflow, temperature, water level in
production well and required injection pressure in a well for reinjection may
significantly reduce the costs of energy production. Lower production costs
compensate high investment expenditures and reduce the energy prices down
to an acceptable level, competitive in relation to conventional energy sources.
In the research project, we used the TOUGH2 simulator to select
configuration of geothermal doublet and to estimate the discharge of
potential geothermal installation localized in the vicinity of Kalisz and based
upon the existing Zakrzyn IG-1 well. Considering the measurements and
other information gained during the drilling operations, the conceptual model
was generated. In order to select the optimal configuration of the doublet,
which would ensure the maximum yield, the analysis was carried out on the
influence of production/injection wells spacing on production parameters.
The optimization aimed to determine the minimum spacing which would
guarantee that the injection well would not affect the temperature of fluid
discharged from the production well within the presumed circulation time.
