There are methods of modeling hydrogeological systems implemented at various fields. Static and filtration models were used during hydrogeological studies. The choice of the model is determined by the task. A feature of the filtration models is the most accurate description of the geological structure of the deposit. When describing the nature of hydrodynamic processes at producing wells, the main direction of development was obtained by field modeling methods using geofiltration equations. The reliability of the results of using the geofiltration model is described in detail in The geofiltration model is implemented by describing a partial differential equation. The boundary conditions are described, and the initial data are the geometric and physical parameters of aquifers, the characteristics of their mutual influence, etc .. The main difficulty in creating a model is to ensure that the simulation results correspond exactly to the original. If at this stage we do not take into account the essential properties of the distributed object, then in the end it is possible to get a description of a completely different process. Further, the paper describes the method of determining the parameters of the hydraulic equation used in the construction of a mathematical model of the field. An example of a model describing the geofiltration process is given. To solve the geofiltration equation, a discrete model of the object is constructed. The structure of the approximating link for this class of objects is given. The stages of determining the parameters of the approximating link are described. The method is accompanied by an example of calculations for the Berezovsky section of the Kislovodsk field. The graphs of the input impact functions and the output functions necessary for determining the phase shift are implemented using the developed KALIGOR-MISMATCH software module. This technique is an integral part of the frequency method of synthesis of multidimensional systems, when the input effects to a distributed controller are implemented as a discrete function over space. The method of synthesis of regulators can be used to describe the stability of hydrodynamic systems.
