抽油机井地面设备组合优化与节能技术

抽油机井的各种节能型机电设备的优化配置可以显著提高抽油机井的系统效率。按照可独立进行节能改造的原则,将抽油机井地面系统划分为电控箱、电动机、抽油机三个单元,建立了抽油机井数据库。提出了地面设备合理配置的混合离散变量优化模型,研究了求解策略,并编制了抽油机井地面设备优化组合软件。现场应用结果表明,利用抽油机井地面设备组合优化与节能技术开发的优化软件,可以实现抽油机井地面耗电设备的合理配置,提高系统效率,具有显著节能效果。

A Technique of Combinatorial Optimization and Energy Saving for Ground Equipment of Pumping Unit Well

The system efficiency of pumping unit well can be advanced evidently by the optimal configuration of various energy saving equipment. The ground equipment of pumping unit well is partitioned into three elements on the principle that the energy saving reconstruction can be put in practice independently. The three elements are respectively electric cabinet, electrical motor, and pumping unit. Subsequently, the database is established, the optimum model of mixed discrete variables is put forward in order to configure the ground equipment reasonably, the solution strategies are studied, and the combination optimization software is compiled. The applied results on oil field showed that the reasonable configuration for the ground equipment of pumping unit well can be realized by applying the new combination optimization software, the system efficiency is advanced, and there is an evident energy saving effect.
