This article discusses development of the "Polymer flooding" module for distributed information system of oil fields development analysis. This module is designed to simulate displacement of oil using polymer injection method for 1532 Timur Imankulov et al. enhanced oil recovery and based on modern mathematical model that considers influence of salt and polymer concentrations on viscosity of injected reagent. Also, permeability changes of aqueous phase depending on adsorption of the polymer and residual resistance factor are considered. Results of numerical studies of two-dimensional and three-dimensional cylindrical domain are presented. Main results of numerical experiments compared with laboratory tests and calculations of reservoir simulator Eclipse (Blackoil). Distribution of main technological parameters is obtained and efficiency of oil displacement using polymer (polyacrylamide, gellan) injection is shown. The module of polymer injection of distributed information system for oil field development analysis (ISAR-2) with operational monitoring in real time is developed.
