摘　　要：示功图是了解井下抽油设备工作状况的一个重要手段,是目前各采油作业区掌握现场油井生产动态最常用的一种方法。通过示功图,可以掌握油井工作制度是否合理,找出影响泵效或抽不出油的原因,如果把示功图和液面等资料结合起来分析,还可以了解油层的供液能力。因此,对实测示功图进行正确识别和分析,对于判断泵况及油井生产状况就显得十分重要。Dynamometer diagram is a main means to know the working condition of the downhole pumps, and a most common method to get the production performance of the field oil wells in production area. Using dynamometer diagram can get to know if the working system of oil wells is adaptable or not, find out the causes that effect pumping efficiency and no oil can be produced. By combining dynamometer diagram with data like fluid level to analyze, reservoir fluid production capacity can also be known. Therefore, correct identification and analysis for dynamometer diagram play an important role in the judgment of downhole pump and oil well production conditions.
