Kai Zhang,Yuande Zuo,Hanjun Zhao,Xiaopeng Ma,Jian Wei Gu,Jian Wang,Yongmei Yang,Chuanjin Yao,Jun Yao +8 more
TL;DR: A deep-learning-based model is developed to solve three categories of problems controlled by the subsurface 2D oil/water two-phase flow PDE based on the FNO, a recently proposed high-efficiency PDE solution architecture that overcomes the shortcomings of popular algorithms such as physics-informed neural networks and fully convolutional network.
Journal ArticleDOI
Construction and optimization of adaptive well pattern based on reservoir anisotropy and uncertainty
TL;DR: The results show that the well pattern can perfectly adapt to anisotropic and uncertain reservoirs, and the optimization method can remarkably reduce the computational amount while ensuring the accuracy of the results.
Journal ArticleDOI
Well-Placement Optimization in an Enhanced Geothermal System Based on the Fracture Continuum Method and 0-1 Programming
TL;DR: The results indicate that the well-placement optimization proposed in this paper can improve the performance of an EGS.
Journal ArticleDOI
Simulating two-phase flow and geomechanical deformation in fractured karst reservoirs based on a coupled hydro-mechanical model
TL;DR: In this paper, a coupled hydro-mechanical model for simulating the complex behavior of fractured and karstified porous media is developed, where a two-phase Darcy's equation is used to describe fluid flow in both matrix and fractures, while the free flow in cavities is considered based on an assumption of phase instantaneous gravity segregation.
Journal ArticleDOI
Prediction Model for Subway Tunnel Collapse Risk Based on Delphi-Ideal Point Method and Geological Forecast
TL;DR: In this article, the authors proposed a new method for assessing the risk of collapse in subway tunnels based on the Delphi method, which is applied to an actual project to verify its correctness, and the prediction results have good consistency with the actual tunnel.
