摘　　要：目前,采用常规型游梁式抽油机采油是国际油田开采中最常用的方式,占整个采油作业的60%之多。常规型游梁式抽油机的平衡通常采用气动平衡、液压平衡和机械平衡3种方式,其中机械平衡通常采用曲柄平衡、游梁平衡以及复合平衡的方式实现。本文主要针对抽油机减速器的输出轴转矩进行计算分析,借助MATLAB软件作出曲柄净转矩曲线图,进行对比计算,从而确定不同的平衡方式对抽油机节能效果的影响程度。At present, the conventional beam oil extractor used in the oilfield development production is the most com- monly extraction method, which occupies the entire production more than sixty percent. The conventional beam oil extractor usually adopts three balance ways, or pneumatic balance, hydraulic balance and mechanical balance, mechanical balance usu- ally takes crank balance, beam balance, and combined balance. This paper mainly focused on output torductor of oil extrac- tor retarder to do calculating analysis, and did calculation for crank net torque curve diagram through MATLAB software, so the energy-saving effects of oil extractor for different balance ways were conformed.
