Claim 4:
5. The automatic seismic facies identification method of claim 4, wherein step (e) comprises:
training the seismic facies identification model by using a hybrid loss of a cross-entropy loss function and Dice Loss, wherein a calculation formula of the hybrid loss is expressed as:

Loss=0.7*CE+0.3*Dice  (9);

wherein CE(y, p)=Σi,jΣk=1Cyi,j(k) log pij(k);, Dice

  ;, y is a real seismic facies label of a seismic image; p is a predicted mask of the seismic image; yi,j represents a one-hot coding label corresponding to a pixel at i,j of the seismic) image; and pij(k) indicates a probability that the pixel at the i,j of the seismic image is predicted to be a kth-type seismic facies.
