摘要

A back-propagation neural network model has been used to estimate tight gas sand permeability from porosity, mean pore size, and mineralogical data. The optimal network topology consists of an eight-neuron input layer, two five-neuron hidden layers that use nonlinear sigmoid transfer functions, and a linear single-neuron output layer. The network model has been trained on a data set from a tight gas sand well and tested on some core samples data that were not seen by the network during training. The optimal network architecture was able to estimate back the permeability from the training set within 0.89
