| Abstract: | For three-dimensional multicomponent displacement problem a kind of upwind difference scheme is put forward thick and thin grids are used to form a complete some techniques,such as calculus of variations,energy method and the prior estimates and techniques are adopted.Optimal order estimates in l2 norm are derived to determine the error in the approximate solution.This method is successfully used in seawater intrusion numerical simulation and oil-gas resource estimation. |
