利用功率曲线数据进行游梁式抽油机调平衡的方法，是对电流法、示功图扭矩法等调平衡方法的补充。随着功率测试的普及，该方法的研究越来越受到重视。分析上、下冲程中曲柄平衡块对曲柄轴做功的平均平衡功率与曲柄平衡块位置的关系，结合平均电动机输出功率变化量与曲柄平衡块对曲柄轴做功的平均平衡功率变化量的关系，依据上、下冲程中平均电动机输出功率相等的平衡准则，建立了曲柄平衡抽油机平均功率法平衡调整量计算模型。结合现场生产状况，对模型进行说明与应用拓展，进一步提高模型的实用性。实例计算结果表明，该模型达到上、下冲程平均电机输出功率相等的要求，同时整个冲程中的电机均方根功率由9.4444 kW 减小到8.4237 kW，有利于抽油机节能运行。

The use of power curve data for adjusting balance for beam-pumping unit is a supplement to balance adjustment methods like current method, indicator diagram torque method, etc. With the popularity of power testing, the research on this method has received more and more attention. Analysis was performed of the relationship between the average balance power of crank counterbalance working on crack shaft and the position of crank counterbalance during up and down stroke; and a calculation model was established for balance adjusting amount by average power method for crank balance pumping unit, in conjunction with the relationship between the average motor output power variation and the average balance power variation of crank counterbalance working on the crank shaft, and based on the balance criterion of equal average motor output power during up and down strokes. This model was explained and further applied with the field operation, in order to further improve its practicability. The practical calculation results show that the model meets the requirement that the average motor output powers should be equal during up and down strokes, and the root-mean-square power of motor during the whole stroke was reduced from 9.444 4 kW to 8.423 7 kW, which helps energy-saving.
