Claim 1:
2. The automatic seismic facies identification method of claim 1, wherein the step of obtaining and preprocessing post-stack seismic data to construct a sample training and validation dataset comprises:
(a1) collecting and preprocessing original seismic data to obtain the post-stack seismic data; and normalizing an amplitude of the post-stack seismic data to [0, 1];
(a2) equally dividing the post-stack seismic data into N section blocks along a crossline direction, wherein each of the N section blocks consists of a first sub-block and a second sub-block; the first sub-block is configured as a training set, and the second sub-block is configured as a validation set; N is a positive integer greater than 2; and a number of the first sub-block is not less than a number of the second sub-block;
(a3) adjusting a size of a seismic section image to a multiple of 16 by using a linear interpolation method; and
(a4) subjecting the seismic section image to data augmentation by right-and-left flipping and Gaussian noise transformation.
