深水防喷器组液压控制系统仿真(英文)

Simulation of hydraulic control system of deepwater subsea blowout preventer stacks

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。

The oil and gas industry has been constantly affected by numerous blowouts since it was evolved.Blowout which is caused mainly by kick,leads to loss of valuable reserves and also causes property damage along with loss of life.Subsea blowout preventer （BOP）stack is the key equipment which ensures the safety of wel bore operation.Once the blowout occurs,the control system of BOP wil actuate the corresponding valve and close the preventer within a spec-ified time.This paper investigated the dynamic behavior of hydraulic control system of deepwater subsea BOP stacks.Mathematic simulation models of the ram and annular preventers are estab-lished by using SimulationX software.Different cases are studied to verify whether it is appropri-ate to be operated according to API requirements at the water depth of 1 524 m.
