随着油田发展到中后期,井口采出液含水逐年上升,使联合站进液量增多,造成地面工艺设施超负荷运行,特别是加热系统、库容、以及其他耗能设备必须更新,由于资金限制,往往不能满足现场需要,使油水处理成本年年上升,且指标控制越来越难,为了合理利用现有设备设施,减少处理难度,将部分联合站的油井产出液进行初步分离,一部分含油极少的污水直接进入后端处理,可以最大化使用现有设备,达到油水合格分离。 With the development of oilfields in the middle and later stages, the water content of production fluid in the well head rises year by year, increasing the amount of liquid entering the joint station, resulting in overloading of ground process facilities, especially the heating system, storage capacity, and other energy consuming equipment. Due to financial constraints , Often can not meet the needs of the site, so that the cost of oil-water treatment increases year after year, and the index control more and more difficult, in order to make rational use of existing equipment and facilities to reduce the difficulty of handling, some of the joint station oil well fluid preliminary separation, part of the oil Fewer sewage directly into the back-end treatment, you can maximize the use of existing equipment to achieve qualified oil and water separation.
