| 中文摘要: |
| 研究油气注采井气密封封隔器(简称封隔器)胶筒在不同工况下的密封性能。结果表明:Yeoh模型作为本构模型能够准确描述封隔器胶筒橡胶材料的超弹性行为;在各种工况下,半永久式、可取式和永久式封隔器胶筒的接触压力均高于流体压力,封隔器不会发生密封失效现象,但可取式封隔器边胶筒存在一定的强度失效风险。本研究可为油气注采井长期安全和高效运行提供参考。 |
| 英文摘要: |
| The sealing performance of the rubber cylinder of the gas sealing packer(referred to as the packer) in oil and gas injection and production wells under different working conditions were studyied.The results showed that the Yeoh model,as a constitutive model,could accurately describe the hyperelastic behavior of the rubber material of the packer rubber cylinder.Under different working conditions,the contact pressures of the semi-permanent,retrievable,and permanent packer rubber cylinders were higher than the fluid pressures,so that sealing failure of the packers did not occurre.However,there was a certain risk of strength failure for the retrievable packer edge rubber cylinder.The research could provide reference for the long-term safe and efficient operation of oil and gas injection and production wells. |
