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。As the most important equipment in oil production, pumping unit has a great potential in energy-saving. An energy-saving control strategy of time-sharing start and interleaving run is presented in this paper for pumping units, which is based on the periodic alternation characteristics of loads and the cluster distribution advantage of pumping units in different production areas. The active power load curve similar to sine wave is given, and the control scheme and optimization model of time-sharing start and interleaving run for pumping units are proposed. Finally, the examples of five pumping units working with identical loads and different loads are optimized with the proposed strategy to realize load leveling, and the energy-saving effects under synchronous run and time-sharing start and interleaving run are calcu- lated. The results indicate that the control strategy put forward in this paper is effective in load leveling and energy-sav- ing.
