| The vast majority are used in oilfield water injection to maintain pressure in the way of doing development. This makes the water system has become a major component of oil production system, it is one of the basic guarantees oil production. With good water injection, water injection enough as the target, keeping oilfields, it has an important role to improve oil recovery. From the point of view of energy saving, water is a major energy consumer oilfield development, according to statistics, water system power consumption about 30% to 40% of the total electricity consumption of oil. Well oilfield water injection system, for energy saving, lower operating costs oilfield production has a very important significance. Including crude oil sewage water and the station prolapse other types of oily wastewater. Oilfield wastewater treatment based on oil production, environmental and other factors that can have a variety of ways. When the oil needs water, oilfield reinjection of treated sewage after the formation, this time to for suspended solids, oil and many other indicators of strict control, to prevent the formation of its harm.In this paper, the development and construction to extend the oil pipeline Jingbian Oil Production Plant eighth joint station sewage reinjection system as the background, was designed to improve the water reinjection rate framework, establish water reinjection of functional requirements, the establishment of the system software and hardware systems, in order to achieve water reinjection process control technology. After testing and debugging, the indicators have reached the design of the system design requirements. The water reinjection system is stable, reliable, cost-effective high automation and control systems, to better meet the flow of operations, requiring on-site security management and production scheduling, the system greatly increase the level of automation oilfield water injection process control. |
