The oil production prediction is a key to prediction or evaluation of conformance control effect after the scheme implementation. Based on the theory of BP neural network, by analyzing the influencing factors of conformance con- trol effect, the neural network prediction model for conformance control was established by employing the toolbox functions in the Matlab neural network. Through the analysis of the model forecast effect and practical application,it was considered that the oil production predicted by the BP neural network was consistent with the actual one, which had smaller relative error and high reliable. The model can be used to predict the conformance control production.
