Title: Permeability prediction method based on improved BP neural network
Abstract: The traditional BP algorithm has slow convergence rate,and is easy to fall into local minimum.It is improved based on Kozeny-Carman equation and the study of Yang Zhengming,and a three-layer feedforward BP neural network model for permeability prediction is established by means of MATLAB neural network toolbox.The simulation training of the improved neural network model is carried out.The result shows that the improved model has faster convergence rate and higher accuracy.The values predicted by the model are consistent with the laboratory test values,and the relative error is less than 10%,so it can completely meet the accuracy demand of well site.
