Deposition type identification model establishment method, deposition type identification method and related device

The invention discloses a deposition type identification model establishment method, a deposition type identification method and a related device. The deposition type identification model establishing method comprises the steps that a sample set is obtained according to multiple selected well logging curves of at least one well and deposition type data, and samples in the sample set comprise curve segments and deposition types of all the selected well logging curves within a certain depth range of the corresponding well; and setting a network structure and network parameters of the deep neural network according to a set rule, and training the set deep neural network by adopting a periodic attenuation type learning rate through the sample set to obtain a deposition type identification model for predicting target well deposition type data. The model established through the method can quickly and reasonably complete prediction of target well deposition type data based on well data; the loss function is optimized
