摘要:
采用ANSYS建立套管接头的轴对称模型,着重分析一种特殊螺纹套管接头柱面/球面密封结构的密封性能,分别对3种工况(机紧、机紧+拉伸、机紧+内压+拉伸)进行求解,获得了密封端接触压力和等效应力的分布规律,对比分析了不同工况下密封端接触压力和等效应力,揭示了拉仲载荷和套管内部压力对结构密封性的影响.结果表明,该柱面/球面密封结构的接触压力和等效应力符合密封要求,为特殊螺纹套管接头的进一步优化设计提供理论指导.
Abstract:
Using ANSYS to establish an axisymmetric model of the casing joint, focusing on the analysis of the sealing performance of a special threaded casing joint cylindrical/spherical sealing structure, respectively for the three working conditions (machine-tight, machine-tight+tension, machine-tight+internal) The distribution law of the contact pressure and equivalent stress of the sealing end is obtained, and the contact pressure and equivalent stress of the sealing end under different working conditions are compared and analyzed, revealing that the tensile load and the internal pressure of the casing have an impact on the structure. The impact of sealing performance. The results show that the contact pressure and equivalent stress of the cylindrical/spherical sealing structure meet the sealing requirements, which provides theoretical guidance for the further optimization design of special threaded casing joints.
