In the process of field development, it’s extremely important to exactly predict the production for development, disposi?tion readjustment and measures efficiency improvement. GM(1,1)grey model predicting method has the benefits of lower cost, high exactness, fast computer speed and easy operation, especially for the well production index prediction. Aiming at the irrational?ity of the traditional process of modeling and predicting of GM(1,1)grey model, the original data was preprocessed to increase the smoothness of initial data series. Meanwhile, random data point was regarded as a known condition to select model boundary condi?tions, and a developed GM(1,1)grey model was established. According to actual production data, it tests that the prediction accura?cy is improved by this new model. The result is reliable so that it can provide references for production decision.
