description: This work is devoted to the study of the colmatization effect in the process of reservoir pressure maintenance. The study is based on numerical modeling of the coupled problem of the equation of filtration in a porous medium and the equation of suspended particle transport by the finite element method and includes both internal and external colmatization. The theoretical foundations of the finite element method as applied to differential equations of hyperbolic type are discussed in this paper. Models have been developed in the open source software FreeFEM++ for filtration with particle concentration transfer in an open wellbore, in a fixed fracture, as well as in an auto-fracture. The sensitivity of the model to the main parameters was analyzed, the fields of determining variables such as pressure, porosity and permeability were obtained and analyzed, on the basis of which conclusions were made about the degree of influence of colmatization on the filtration-capacitance properties of the formation.
