摘　　要：为解决渤海某油田FPSO原油处理系统使用中单个设备故障下线检修时需要整个生产系列下线从而影响油田运行生产时率及油田产量的问题,对现有生产流程进行改造,分析FOXBORO公司PSD关停保护控制系统的作用原理,根据改造后的流程情况制定相应的关停联锁保护逻辑,流程改造及系统优化后,2个生产系列可实现互联互通,在单个生产系列中出现设备故障下线检修时产液可通过另一个生产系列正常处理,同时在出现工况异常时也能实现设计关停保护动作,使原油处理系统的稳定性得到增强。During the operation of a FPSO crude oil treatment system in Bohai oilfield,the whole production series needs to be offline when a single equipment offline for maintenance,which affects the oil field operation time rate and oil field output.In order to solve this problem,the production process was optimized.By analyzing the function principle of FOXBORO PSD shutdown protection control system,the corresponding shutdown and interlock protection logic was formulated according to the process situation after the transformation.After the process transformation and system optimization,the two production series of crude oil treatment system were interconnected and it can also realize the design shutdown protection when the working condition was abnormal which enhances the stability of crude oil treatment system.
