This article is devoted to research the impact of openness of cracks on their permeability for the Tournaisian-Famennian deposits in the Solikamskaia depression. Occurrence of fractured zones within these deposits is confirmed by data of many surveys. Receiving the parameters of cracks is based on the interpretation of hydrodynamics research materials using the Warren – Root technique. The dependence between permeability and openness is constructed and analyzed on the first stage. It is established that the dependence is complex nonlinear. To research more details one-dimensional regression is constructed. As a result, four classes, characterized by special permeability dependence on openness are determined. The assessment of the availability of these classes is verified by stepwise linear discriminant analysis. This method is useful for solving such a predictive task. Linear discriminant functions are received. The use of these functions confirms correctness of four classes determination with permeability of cracks depends on their openness. There is no single type of permeability dependence on openness because there are four diapasons where permeability has different character. The resulting equations of regression help us to find the magnitude of reservoir permeability. These equations allow us to raise the effectiveness of geological-hydrodynamic modeling.
