| Abstract: | The study of reservoir heterogeneity is the basic science of deciding residual oil distribution. Well testing data are responses of production performance, including a lot of dynamic information of reservoir characterization. By the method of inversely analyzing well testing data, reservoir heterogeneity in space and different time can be decided. The distribution of reservoir permeability near the wellbore can be determined more exactly by the improved method of ISA (Inverse Solution Algorithm). The distribution of reservoir per-meability in regional field from several well testing pressure data can be determined by the technology of stochastic modeling. Application in oilfield indicates that the method of deciding reservoir heteroge-neity from well testing data could be a widely appropriate technology |
| Keywords: | well testing data distribution of permeability inverse solution algorithm stochastic modeling forecast |
