摘要
海上石油生产设施在日常生产过程中,如果关断阀、控制阀等设备意外突然关闭时,生产流程将出现大幅波动,极易造成单元关断或全生产关停。为有效降低因生产流程波动造成的单生产序列关停或者全生产关停的次数,减少油井电潜泵意外停机次数,本文基于国产和利时中控系统,实现油井手动“一键降频”与自动分级停井功能优化,在安全功能不受影响的前提下,利用将电潜泵运行频率手动一键降至基准频率的功能,让中控主操有时间采取最有效的紧急操作避免关停,并且当触发某个单序列生产关停信号时,自动关停高含水井,最大限度减少原油产量损失。油井手动“一键降频”功能的创新开发与自动分级停井功能的创新优化,经济效益明显、推广性强,可推广到其他海上设施,特别是已经实施或者正在实施中控系统国产化的海上设施。
In the daily production process of offshore oil production facilities,unexpected and sudden closures of shutdown valves,control valves,and other equipment can cause significant fluctuations in the production process,leading to unit shutdowns or complete production stoppages.To effectively reduce the number of shutdowns of individual production sequences or complete production stoppages caused by process fluctuations and minimize the number of unexpected shutdowns of oil well electrical submersible pumps(ESPs),this article presents an optimization of the manual"one-button frequency reduction"and automatic graded shutdown functions for oil wells based on the domestic HollySys central control system.Without compromising safety functions,the feature allows for manually reducing the ESP operating frequency to a baseline frequency with a single button press,giving the central control operator time to take the most effective emergency actions to avoid shutdowns.Additionally,when a signal for the shutdown of a single production sequence is triggered,the system automatically shuts down wells with high water content,minimizing the loss of crude oil production.The innovative development of the manual"one-button frequency reduction"function and the optimization of the automatic graded shutdown function offer significant economic benefits and strong scalability,making them suitable for promotion to other offshore facilities,especially those that have implemented or are in the process of implementing the domestication of their central control systems.
