The article proposes to use the results of indicator research methods to clarify the geological structure of deposits. Comparing the dynamic filtration rates of fluids with the actual results of indicator studies, it is possible to determine the preferred directions and orientation of cracks in carbonate reservoirs. In order to study the spatial orientation of cracks in carbonate reservoirs based on the results of tracer studies, a geological-hydrodynamic model of the Tournaisian deposits of 101 deposits of the Novo-Elkhovsky deposit was used. At the same time, geological and technological modeling with an iterative method of creating models is used as an implementation of this approach. The filtration model was selected on the basis of the physicochemical properties of the carbonate sediments fluids saturating the formation, taking into account the double porosity and double permeability of the object under study. In the filtration model, the size and number of cells of the geological model were saved. The adaptation of the parameters of the filtration model according to the development history was carried out in two versions. In the first variant, the parameters of the filtration model were adapted without taking into account the results of indicator studies. The values of permeabilities in the directions of the X, Y and Z cracks were assumed to be equal. In the second variant, the parameters of the filtration model were adapted to reflect the results of indicator studies. As a result of adaptation, the values of permeabilities in the directions of the X and Z cracks were obtained more than in the Y direction. The use of directional orientation in modeling allowed us to establish the main direction of the cracks along which the fluid is filtered. Application of the results of indicator studies in the construction and adaptation of parameters of the reservoir filtration model increases the degree of compliance with the geological and technological model and the real object of development.
