Abstract: It is important to predict the productivity of wells accurate-ly in the practice of exploiting of an oil field by means of predic-tion filter model (PEM) used in seismic exploration. The result of calculation from the data of Huabei oil field indicates that the prediction based on PFR is acceptable, and some helpful ideas can be extracted. Compared with other models, PFM is charac-terized by its simple algorithm, fast calculation and high coinci-dence.

Key words: productivity of well, prediction filter, predic-tion of productivity
