Abstract.

The article considers a stress-strain state of the rubber seal in the collar-type packer. These packers are self-sealing and are used to check pressurization ability of oil and gas wells, and they are actuated by the pressure in the well.

To solve the problem, a space-time finite element is used in the software package “MІRELA+”. As a result of the numerical calculation, values of displacement, strain and stress distributions in the rubber element were obtained with taking into account viscous-elastic deformation. Value of the collar sediment was calculated depending on the load and with taking into account rheological properties of the material.

Keywords:

stress-strain state, viscous elasticity, rubber, collar-type packer, self-sealing collar
