摘　　要：确定抽油机曲柄净扭矩和调整其平衡有两种常用方法,即功率曲线法和扭矩曲线法。通过分析抽油机现场采集的数据,编写MATLAB程序利并用迭代法求解抽油机的最佳平衡位置,验证了这两种曲柄平衡调整方法的准确性和实用性,并总结出两种方法的优缺点,提出了相对适用的调整方法。There are two common methods for determining the net torque of the crank of pumping unit and adjusting its balance, namely the power curve method and torque curve method. The MATLAB program for calculating the optimal balancing position of the pumping unit by using iteration method is written, and the accuracy and practicality of these two crank balancing adjustment methods are verified according to the analysis of the data of pumping units collected from the on-site. The advantages and disadvantages of these two methods are summed up, applicable adjusting measures are proposed.
