【摘要】：作为油田生产中最基本的设备,抽油机拥有巨大的节能潜力。基于抽油机负荷呈周期性交变的典型特点,利用油田各采油区块中多台抽油机集群分布的优势,提出了抽油机群分时启动交错运行节能控制策略。本文设计了抽油机群分时启动交错运行控制方案,推导了抽油机有功功率负荷的类正弦曲线,建立了抽油机群分时启动交错运行优化模型,分别对5台同负荷和异负荷抽油机进行了分时启动交错运行负荷平抑优化,计算分析了其在同时同步运行与分时启动交错运行两种情况下的节能效果。算例表明,所提出的控制策略具有良好的负荷平抑和节能效果。
[Abstract]:As the most basic equipment in oil field production, pumping units have great energy saving potential. Based on the typical characteristics of periodic alternating load of pumping units, the advantage of cluster distribution of multiple pumping units in various oil production blocks is utilized. An energy saving control strategy is proposed for the staggered operation of pumping unit group time-sharing start-up. In this paper, the control scheme of the pumping unit group time-sharing start-up staggered operation is designed, and the sinusoidal curve of the active power load of the pumping unit is derived. The optimization model of staggered operation of pumping units was established, and five pumping units with the same load and different loads were optimized respectively. The results show that the proposed control strategy has good load suppression and energy saving effect.

【正文快照】： 随着能源紧缺与环境问题的日益加剧,节能减排已成为当前社会经济发展的必然选择。我国的油田大多为低渗透性油田,不像中东地区的油田有很强的自喷能力,因而需要大量使用抽油机从地层中抽取原油[1]。我国目前的抽油机数量在10万台以上,电动机装机总功率超过3 500 MW,每年耗电量
