The invention relates to the technical field of crude oil production, in particular to a rod-pumped well standard work diagram calibration method based on unary distance clustering, which comprises the following steps: collecting real-time work diagram data of an oil well, cleaning abnormal data including zero value, null value and negative value of the real-time work diagram data, and performing clustering analysis to obtain the standard work diagram of the oil well. And determining the most stable indicator diagram with the highest occurrence frequency, and calibrating the indicator diagram as a standard indicator diagram. The accuracy of the standard indicator diagram can be improved, the setting time of the standard indicator diagram is shortened, and the working efficiency is improved. 本发明涉及原油生产技术领域，特别涉及一种基于一元距离聚类的抽油机井标准功图标定方法，包括采集油井的实时功图数据，对实时功图数据进行异常数据清洗，所述异常数据包括零值、空值及负值，通过聚类分析，确定最稳定、出现频次最高的功图，标定为标准功图。本发明能够提高标准功图准确性，降低标准功图设置时间，提高工作效率。
