description: This work is devoted to the study of the effect of a detonation wave on the packer element arising in the process of selective perforation of the casing and productive formation. The main objectives are: 1. development, verification and validation of finite element models of packer, casing and shaped charge; 2. analysis of the residual energy of the detonation products of the shaped charge by the finite element method; 3. analysis of the impact of the detonation wave on the packer element in the case of initiation of one or more explosive charges by the finite element method; In the course of the work an analysis of the scientific literature was carried out, the results of which identified the main problems and topical areas of research. A mesh convergence analysis for the finite-element model of the packer was performed, as well as validation of the detonation process, cumulative jet formation, target penetration and shockwave loading. As a result, the maximum permissible axial force for the presented packer design is determined. The residual energy of the detonation products for a shaped charge of the ZPK-105 type is estimated. The distance between the packer and the charge at which the force value exceeds the maximum permissible axial force is determined.
