| Abstract: |
| The working principle of compressed packers used in oil and gas production，as well as research progress of the material and structure of the packer rubber and the structure of the spacer ring were introduced.It was recommended to use hydrogenated nitrile rubber with good comprehensive performance and fluororubber with good high-temperature resistance as the main materials of the packer rubber，improve the formula of the compound to obtain high performance rubber material，improve the rubber structure to increase its effective contact length and contact stress with a limited number of rubber，and design a structurally reliable spacer ring to improve the sealing performance of the packer and extend its service life effectively. |
