| Abstract: | The control equations, initial conditions and boundary conditions related to low permeability flow with moving-boundary are given in dimensionless representations. Subsequently, meshless methods were introduced to simulate these problems and numerical results were obtained. Gringarten-Bourdet graphs are used to analyze the bottom well pressure. To investigate the propagation of moving-boundary, a method to determine the position of moving-boundary is presented and the propagation curves of moving-boundary in different parameters are discussed. |
