ROCK CRACK INFORMATION IDENTIFICATION METHOD AND SYSTEM BASED ON VARIATIONAL AUTOENCODER

The present disclosure pertains to a rock crack information identification method and system based on a variational autoencoder, and belongs to the technical field of rock mechanical fracturing tests in petroleum engineering. A micro-resistivity scanning imaging test and a computed tomography (CT) scanning test are performed on each rock specimen to obtain a two-dimensional micro-resistivity distribution image and a three-dimensional CT scanning image of the rock specimen for training, and an initial variational autoencoder is trained to obtain a trained variational autoencoder. In an actual application, a two-dimensional micro-resistivity distribution image of a rock to be tested is obtained first, and the three-dimensional CT scanning image is reconstructed by using the trained variational autoencoder, such that rock crack information of the rock to be tested is accurately determined with low costs.
