摘要
井下安全阀是一种用于海上油气田作业管柱的安全控制装置。为确保油气田生产安全、顺利进行,有必要对井下安全阀阀板实施关闭瞬时的冲击性能有限元模拟分析。根据安全阀现场实际工况,建立了阀板瞬时冲击模型和载荷。通过有限元分析,得出了阀板设计时的强度要求,得出了阀板增加缓冲机构的必要性和适用条件。为安全阀阀板和阀座的设计提供了理论参考,也为安全阀自平衡机构的设计提供了设计依据。
SSSV is a type of safety control device used on offshore oil&gas operation strings.In order to ensure production safety,it is necessary to conduct finite element analysis on the impact performance of SSSV plate.According to the actual working condition of the SSSV,the instantaneous impact model and load of the valve plate are established.Through the finite element analysis,the strength requirements of the valve plate design are obtained,and the necessity and applicable conditions of adding buffer mechanism to the valve plate are obtained.This paper provides a theoretical reference for the structural design of valve plate and valve seat,and provides a design basis for the design of safety valve self-balancing mechanism.
