Patent number: 11934488Abstract: The present disclosure provides a method and system for constructing a digital rock, and relates to the technical field of digital rocks. According to the method, a three-dimensional (3D) digital rock image that can reflect real rock information is obtained using an image scanning technology, and the image is preprocessed to obtain a digital rock training image for training a generative adversarial network (GAN). The trained GAN is stored to obtain a digital rock construction model. The stored digital rock construction model can be directly used to quickly construct a target digital rock image. This not only greatly reduces computational costs, but also reduces costs and time consumption for obtaining high-resolution sample images. In addition, the constructed target digital rock image can also reflect real rock information.Type: GrantFiled: September 10, 2020Date of Patent: March 19, 2024Assignee: China University of Petroleum (East China)Inventors: Yongfei Yang, Fugui Liu, Jun Yao, Huaisen Song, Kai Zhang, Lei Zhang, Hai Sun, Wenhui Song, Yuanbo Wang, Bozhao Xu
