摘　　要：中国海洋石油某FPSO生产水系统流程主要依靠水离心机进行处理,实际处理效果并不理想,随着生产水量的不断增加,为满足环评要求,需要对现有生产污水处理系统进行改造。经过研究,利用FPSO现有的2个不合格原油舱代替污油水舱功能,将2个污油水舱和2个燃料油舱改造成两级生产水沉降舱,并在2个雨水舱中增加生产水沉降舱浮油收集功能,以达到生产水处理流程缓冲和扩容的目的,同时为在役FPSO舱室功能调整以解决生产中遇到的难题提供了新思路。The process design of a certain FPSO production water system mainly depends on the water centrifuge,but the actual treatment effect is not ideal.With the increase of production water,the existing wastewater treatment system needs to be reformed to meet the environmental assessment.Through the study,the existing two unqualified crude tanks of FPSO are used to replace the slop tank,and the two slop tanks and two fuel tanks are transformed into two stage production water sedimentation tanks.And the oil collection function of the production water settling tank is added to the two rainwater tanks,so as to achieve the purpose of buffering and expansion of the production water treatment processing and provide new method for function adjustment of FPSO in service.
