利用振动分析方法对抽油机井故障进行诊断．首先将原函数（原函数可以是悬点载荷对间函数、悬点加速度－时间函数、悬点载荷－悬点泣移等函数）作离散化和必要的预处理后，对其进行幅值域、时域和频域分析，从中找出敏感特征函数作为判别故障的依据．本文通过对悬点载荷－悬点位移（即示功图）的振动为示例进行了分析，给出了寻求故障特征值的振动分析方法，又通过对不同故障示功图的三域分析，得出了一些初步的结论，为抽油机井故障诊断开辟了一个新的途径，为下一步大型数据库的建立打下了基础． Using vibration analysis method to diagnose the fault of pumping well. Firstly, the original function (the original function can be a function of the load-to-load inter-pair function, the acceleration-time function of the suspension point, the function of the load of the suspension point, etc.) is discretized and necessary preprocessing, , Time domain and frequency domain analysis, find out the sensitive characteristic function as the basis to judge the fault. In this paper, we analyze the vibration of the load-suspension point displacement (ie, dynamometer), and give the vibration analysis method to find the eigenvalues ​​of the fault. By analyzing the three fields of the different failure indication diagrams, Some preliminary conclusions are drawn, which opens up a new way for fault diagnosis of pumping wells and paves the way for the establishment of large-scale databases in the next step.
