摘要
Production performance data have seldom been involved in stochastic simulation; thus, it is difficult to describe such production performance as pressure and yield using the geologic model. We present a method for well test data constrained stochastic modeling. The initial model, which is built through stochastic simulation, is updated using simulated annealing algorithm until the model matches well test data. In this process, bottom hole pressure is calculated using analytic solution combined with numerical solution; this may save more than 90% of computation time. A case study shows that the final model has been improved and matches well test data. © 2020, Editorial Department OIL GEOPHYSICAL PROSPECTING. All right reserved.
