| description | The invention discloses a grid model generation method for a well cementation engineering fluid displacement process. The grid model generation method comprises the following steps: 1, determining node parameter values of grid nodes in the well depth flowing direction according to obtained actual measurement data in the well cementation process; and step 2, generating a grid model for the well cementation engineering fluid displacement process according to the node parameter values. According to the method, the numerical simulation efficiency is greatly improved by optimizing the number of grids in the well depth flowing direction. Meanwhile, according to the method, the grid orthogonality is better by exploring the correlation between the centrality and the circumferential encryption method and adjusting the circumferential grid distribution rule, and therefore the simulation robustness is guaranteed. Besides, the method further performs hole deviation angle adjustment on the grid coordinates, so that the gr |
