Research on Condition Prediction of Rod Pumping System Based on Grey Prediction Model

In order to track the faults that occur in the downhole operation of the rod pumping system in time for targeted processing, it is meaningful to predict the condition. The eigenvalues of the pump power diagram are predicted by using the gray prediction model, and the predicted values are compared with the original values to analyze the errors. The results show that the prediction model has a high degree of fitting and has a good effect on the fault prediction of the rod pumping system.
