井喷是海洋石油安全钻探生产的重要威胁,人为操作失误或元器件失效都可能导致井喷。防喷器组(BOP)安装在水下井口头,是控制井喷的核心部件,一旦发生井喷,BOP控制系统驱动阀门关闭井口,保证油井的安全。研究了深水防喷器组包括其液压控制系统的功能,在系统仿真软件SimulationX中建立防喷器组的详细模型,包括环形防喷器和闸板防喷器及防喷器组的液压控制系统。仿真分析了1 524 m水深下防喷器在不同操作顺序下的封井过程,验证了BOP阀门关闭所用时间符合API规范要求,仿真结果与平台实测数据基本吻合。
Blowout is an important threat to the offshore oil safety drilling production, man-made operation errors or failure of components may lead to blowout. BOP installed in the underwater wellhead, is the core of blowout control, blowout, BOP control system to drive the valve to close the wellhead, to ensure the safety of the well. The function of deepwater BOP stack including its hydraulic control system was studied. Detailed models of BOP stacks were built in SimulationX software, including hydraulic control system of annular blowout preventer, ram BOP and BOP stack . The shutdown process of BOP valves at different operating sequences was simulated and analyzed under 1 524 m water depth. The time required to close BOP valves was in accordance with API specifications. The simulation results were in good agreement with the measured data of the platform.
