On the basis of summarizing and discussing the gamma inversion, we point out that an analytic method of volume attribute is very important. The method integrates multiple stepwise regression and cross verification to optimize and combine the attribute, adopts the convolution factor to eliminate frequency difference between the seismic and logging data, uses the neural network as a matching and predicting tool. Because of its religious theoretic base, the method is more accurate than other ones.
