| 中文摘要: |
| 介绍油气开采用压缩式封隔器的工作原理以及封隔器胶筒的材料与结构和隔环的结构的研究进展。建议封隔器胶筒的主体材料采用综合性能好的氢化丁腈橡胶和耐高温性能好的氟橡胶；改进胶料配方，以获得高性能的胶筒橡胶材料；在有限的胶筒数量下，改进胶筒的结构，增加其有效接触长度和接触应力；设计结构可靠的隔环，有效提高封隔器的密封性能和延长其使用寿命。 |
| 英文摘要: |
| 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. |
