摘　　要：为了验证游梁式抽油机优化控制技术在抽油机上的应用效果,在大庆油田采油工程技术研究院的标准井上,通过贴应变片的方法,分别测定在常规工频和优化运行状态下抽油机3轴(电机轴、减速器输入轴和输出轴)扭矩的变化情况,并进行对比分析。分析结果表明,游梁式抽油机采用运行过程优化控制技术能够明显降低电机轴、减速器输入轴和输出轴的扭矩,且电机轴的扭矩降幅最大,减速器输入轴的扭矩降幅次之,减速器输出轴扭矩降幅最小;不同平衡率下,电机轴扭矩、减速器输入轴和输出轴扭矩峰值降低的幅度也不同;在300、600和800 m 3种动液面下,电机轴和减速器输出轴的扭矩交变幅度都降低,降低比例为36.8%～64.1%。To verify the application of the optimized control technology to beam pumping unit, by means of pasting the straining gauge, the torque variations of the unit＇ s three shafts including motor shaft, reducer input shaft and reducer output shaft were measured respectively in the conventional operating frequency condition and in the optimized operating condition. A comparative analysis of them was conducted. The beam pumping unit which adopts the optimized control technology of operating process can reduce the torque of the three shafts remarkably. The torque decrease of motor shaft is most remarkable, that of reducer input shaft is in the second place and that of reducer output shaft is slightest. The torque peak value decrease of the shafts is also different in different balance rates. At the three liquid levels the alternating amplitude of torque of motor shaft and reducer output shaft will decrease and the decrease proportion is between 36. 8% and 64. 1%.
