description: Topic of the final qualification work: "Numerical analysis of the packer with large gaps in the seal zone". This work is devoted to the calculation of the sealing element of the packer and optimization of its shape to increase the performance of the rubber seal. Tasks that were solved in the course of the work: 1. Creation of a finite element model of the rubber seal of the HEX 350-700 packer according to the given drawing. 2. Identification of the compaction area with the maximum value of destructive stresses and numerical calculation of stresses at this point. 3. Modernization of the seal shape in order to reduce stresses in the hazardous area. 4. Numerical calculation of the stresses of the modernized sealing form. The work was carried out in the ABAQUS software package, which uses the finite element method to obtain the calculation results. As a result, a finite element model of the rubber seal of the packer was created, a numerical calculation of the resulting model was made, and the values ââof the breaking stresses were determined. The shape of the model was optimized in order to reduce the breaking stresses, the modified packer was calculated and its breaking stresses were evaluated.
