抽油机井控制柜与电动机匹配适应性研究

Adaptability Research of the Control Cabinet and the Motor of Pumping Unit Wells

随着油田节能技术的发展,各种新兴节能技术应用于油田节能设备中。通过两种节能电动机与三种节能控制柜匹配试验,以有功功率、无功功率、综合节电率等相关参数变化为评价依据,获得不同功率利用率的匹配效果。在考虑新老井中抽油机转矩、电动机转矩及安全系数的情况下,以匹配效果作为指导,评价目前抽油机井节能状况,对电动机和控制柜匹配不合理的抽油机井,实施设备对调,提高了节能设备的利用效率。

Along with the development of energy saving technology in oilfields, all kinds of new energy saving technologies are used for energy saving equipment in oilfield. The matching experiment of two kinds of energy saving motors and three kinds of energy saving control cabinets is carried and then different matching effects of different power efficiency are got by relevant parameters such as active power, reactive power and integrated power saving rate. Considering the torque of the pumping unit and the motor, and the safety factor of new and old wells, the current saving energy status of pumping unit wells is evaluated with the guidance of matching effects. Meanwhile, for pumping wells that have unmatchable motor and control cabinet, exchanging relevant equipment can improve energy saving efficiency of energy saving equipment.
