摘要
为了探讨ST4×2-5M浅水泥线采油树液压系统的性能,对影响液压系统性能的3个关键部件的参数、液压系统的功能和原理等开展研究,在AMESim平台上搭建了闸阀驱动器、水下电磁阀和水下脐带缆模型。以实际产品为依托,研究了系统充压、单个?127.0 mm闸阀启闭、单个?50.8 mm闸阀启闭以及系统紧急关断4种泥线采油树典型工况下的系统性能。研究结果表明:利用水上HPU为系统充压时间不得短于300 s,充压时间超过600 s后压力提升效果不明显;单个?127.0和单个?50.8 mm闸阀的启闭特性由于闸阀及驱动器本身的技术参数不同而相差较大;紧急关断时液压系统泄压能力与脐带缆内径有着直接的关系;4种典型工况下泥线采油树液压系统性能指标均满足设计要求。研究结果对于实际的液压控制系统开发和工程化应用具有一定的指导意义。
In order to explore the hydraulic system performance of ST4×2-5 M shallow mud line Christmas tree,the parameters,functions and principles of the 3 key parts affecting the performance of the hydraulic system were studied,and the models of gate valve actuator,subsea solenoid valve and subsea umbilical cable were built on AMESim platform.Then,based on the actual product,the system performance under 4 typical working conditions of mud line Christmas tree were studied,such as system charging,single?127.0 mm gate valve switching,single?50.8 mm gate valve switching and system emergency shutdown.The study results show that the charging time of the system using supersea HPU should not be less than 300 s,and the pressure increase effect is not obvious when the charging time exceeds 600 s;the switching characteristics of a single?127.0 and?50.8 mm gate valve vary greatly due to the different technical parameters of the gate valve and the actuator themselves;the pressure relief capacity of the system is directly related to the inside diameter of the umbilical cable when emergency shutdown occurs;and under the 4 typical working conditions,the performance indexes of hydraulic system of mud line Christmas tree all meet the design requirements.The study results have certain guiding significance for the development and engineering application of actual control system.
