Fractal Analytical Solutions for Nonlinear Two-Phase Flow in Discontinuous Shale Gas Reservoir
Mathematics, 2022 The paths of a two-phase flow are usually non-linear and discontinuous in the production of shale gas development. To research the influence mechanism between shale gas and water, several integer two-phase flow models have been studied but few analytical

Numerical study of displacement current phase tomography for gas-water two-phase flow
Journal of Physics: Conference Series, 2021 Abstract Electrical Tomography technology is widely used in the research and engineering practice of two-phase flow due to its advantages of non-radiation, non-intrusive and simple equipment structure. However, because of the electrical tomography sensitive field distribution of medium nonlinear (soft), the reconstructed images are often

Simulation of Gas-water Two-phase Micro-scale Flow in Tight Sandstone Reservoir
Journal of Physics: Conference Series, 2023 Abstract China is rich in tight gas reservoir resources, but the production of tight gas wells is greatly affected by water production. In order to further explore the law of tight gas two-phase flow and improve the recovery ratio of a single well.
