The invention discloses a three-dimensional geologic structure modeling method and
system based on SH-LDM and a medium, and relates to the technical field of
deep learning and geologic modeling crossing, and the three-dimensional geologic structure modeling method based on SH-LDM mainly comprises the steps: carrying out the preprocessing of
original data, and obtaining a training
data set and a
test data set; training the multi-
branch self-encoding network by using the first-stage
loss function, and training the multi-condition
diffusion network by using the second-stage
loss function; and according to
soft data and hard data of a real scene, utilizing the trained multi-
branch self-encoding network and the multi-condition
diffusion network to obtain a three-dimensional geologic
structure generation image. By implementing the SH-LDM-based three-dimensional geologic structure modeling method and
system and the medium provided by the invention, high-precision and efficient modeling of a complex non-stationary underground structure can be realized.
