| 摘 要： | 以油井采出液为试验介质研究油井采出液对封隔器丁腈橡胶(NBR)密封件性能的影响。结果表明:在模拟井况下,封隔器NBR密封件出现老化现象,随着浸泡时间的延长,密封件的邵尔A型硬度逐渐增大,拉伸强度和拉断伸长率逐渐下降,老化机理以分子链交联老化反应为主;随着温度的升高,老化速率快速增大;高含水率的油井采岀液对NBR密封件的性能存在负面影响。

| Abstract: | The effect of oil-well produced water on the properties of NBR packer element was investigated using oil-well produced water as test medium.The results showed that,the properties of NBR packer element changed with aging under the simulated well condition.With increase of soak time,the Shore A hardness of the packer element gradually increased,and the tensile strength and elongation at break gradually decreased.The main aging mechanism was cross-linking reaction.As the temperature increased,the aging rate increased rapidly.The oil-well produced water from high water cut wells had negative impact on the properties of NBR packer element. |
