The problem of numerical simulation of polymer flooding on the basis of BrightWaterTM technology - injection of special chemicals in the form of microscopic granules, changing their properties in the porous reservoir over time, is considered. Based on the isothermal multiphase Black oil model the mathematical model is proposed that takes into account the main physical factors of the process, such as activation time of the polymer granules, the change of reservoir properties depending on the concentration of the polymer and its current dynamic state, changing the mobility of water in the bottomhole zone of wells at the injection of solutions of surface active substances. The given model has been implemented in the framework of the parallel hydrodynamic tNavigatorTM simulator and tested on models of real fields. Good agreement between calculated and experimental data, as well as high numerical efficiency of the model was shown.
Key words: numerical modeling, polymer flooding, BrightWaterTM technology, surface-active agents, tNavigatorTM.
