Abstract

The article summarizes the main factors that should be taken into account when developing a methodology to take into account the relationship between the geomechanical state of the rock formation and its filtration properties. The main approaches to solving such problems and their disadvantages are analyzed. The results of the research allow us to establish a functional relationship between the deformation-stress state of the rock formation and its gas permeability. The relationship is based on the analysis of volumetric deformation of the formation and its influence on the filtration characteristics of the medium.
