| Abstract: |
| Through the establishment of finite element calculation model of the packer rubber system based on ABAQUS，and the setting reasonable boundary conditions and material parameters，it simulated the different pressure conditions in water injection process，and analyzed the change of packer rubber length，the friction force with the casing，Mises stress and contact stress statement.The results showed that the maximum stress of the packer rubber concentrated on spacer ring of the top of packer rubber，the changes of friction stress between the packer rubber and the casing corresponded to the material characteristics of the rubber，and the distribution of contact stress was very uneven. |
