注水系统提效降耗的优化管理

Optimization Management of Water Injection System Efficiency and Consumption Reduction

针对胜利油田某厂注水系统因效率低下而产生的高耗能,探索以提效降耗为目标的注水系统优化管理,基于对注水系统及能耗情况的系统调查,采取了分压注水、注水泵匹配提质增效和注水站避峰填谷等多项举措。实施这些技术措施后,某厂的用能总量得到较好控制,其节能效果显著,共计节电11 234 kWh,年节约电费674万元。

The water injection pumping station of oil production enterprises is an important part of the injection and production system.It is not only a large energy consumer but also a large energy saving potential.After more than 40 years of production in a factory in Shengli Oilfield,the pumping station,water injection pump and water injection process related to the water injection system have a certain degree of incompatibility.Therefore,it is of great practical significance to optimize the system to reduce energy consumption.Through systematic investigation of the water injection system and energy consumption,the scientific partial pressure is used to strengthen the efficiency of the plunger pumping station,the water injection pump is matched to improve the efficiency and the water injection station avoids the peak and fill the valley,and the energy consumption of the water injection system is reduced.Energy-saving effect,a total investment of 1.7 million yuan,11 234 kWh of electricity saving after the transformation,annual energy saving of 6.74 million yuan,achieved remarkable results,ensured the smooth operation of the water injection system,the total energy consumption of the whole plant was well controlled.
