摘　　要：以抽油机节能运行为目标,研究游梁式抽油机游梁平衡块的调整问题.依据电机均方根输出功率最小的抽油机平衡准则,利用平衡块调整量与抽油机输出功率改变量的关系,建立游梁式抽油机游梁平衡块调整量的计算模型,并给出游梁平衡块调整的计算公式.数值计算结果表明,用该模型调整抽油机游梁平衡块,可以减小电机的均方根输出功率,有利于游梁平衡抽油机节能降耗和安全运行.In order to achieve energy-saving operation of the beam pumping unit, the adjustment of beam balance weight is studied. According to the balance principle of minimum RMS of electric power, using the relationship between beam balance weight adjustment and output power change of the pumping unit, the calculation model of adjustment amount about beam balance weight is derived, which puts forward the calculation formula about beam balance weight adjustment. Numerical solution shows that, with the application of this model to adjust beam balance weight, RMS of electric power exported by motor is signally reduced,which contributes to the energy-saving and safe operation of the beam pumping unit.
