摘要/Abstract

摘要： 采用动态密封理论，针对带压作业系统中的橡胶密封胶芯问题，利用非线性有限元计算了在井压和
密封外压作用下的变形和应力分布特征，并通过对密封胶芯材料进行了强度和疲劳实验研究，获得了胶芯材料破坏的原因，进而根据计算和实验研究结果，进一步提出了在胶芯内增加钢筋以减小最大剪切力的改进意见，同时进行了理论校核，并以此为基础设计了新型的密封胶芯，从而解决了带压作业装置高压动密封的难题。

Abstract: The rubber seal issue under operating system has been studied by the theory of dynamic sealing. The deformation and st ress dist ribution of rubber material were calculated under the well in - pressure and sealing out - pressure using the non -
linear finite element . Through the experimental study of the rubber st rength and fatigue, the intensity limit and the fatigue life were obtained. According to the study results, a new type of sealing equipment was designed by adding the reinforcing steel bar into rubber core to reduce the maximum shear st ress, so as to solve the problems of dynamic seal under hyperbaric pressure.

Key words: Oil - water well , Operation under pressure , Dynamic seal
