摘要: 介绍了深水油气田水下复合电液控制系统的基本组成和工作原理,对脐带缆紧急放空的工作原理进行了分
析。利用AMESim 液压仿真软件为水下复合电液控制系统建立仿真模型,依据南海某油田水下控制系统的基本参数
进行参数输入,对4 种不同液压管径的紧急放空时间进行仿真,绘制出口流量、水下蓄能器气体压力、水下蓄能器气体
体积的时间变化曲线,根据仿真结果选择合适的液压管径。将仿真结果与国外对该项目仿真结果进行对比,两个结果
相差5% 以内,验证了仿真模型和仿真结果的正确性,同时,仿真结果可以为水下控制系统设计和脐带缆选型提供技
术参考。

Abstract: The composition of subsea multiplexed electrohydraulic control system and the working theory of umbilical ESD
vent down in deepwater oil and gas field are introduced. The model is established by AMESim software,with parameters based
on a south China sea oilfield. By simulating the ESD vent down with 4 different tubing size,we get the curves of vent flow
rates,volumes and pressures of subsea accumulator. The proper tubing size was chose based on the simulation results. The
difference is less than 5%compared to the foreign simulation results. The result can provide reference for subsea control system
designing and umbilical selecting.

Key words: ESD vent down, umbilical, simulation, hydraulic tubing size, selection
