Modeling the Process of Polymer Injection Into the Reservoir Taking Into Account the Shear Rate
https://doi.org/10.18599/grs.2025.4.8
Abstract
The paper is devoted to the analysis of the influence of the shear rate on the results of hydrodynamic modeling in reservoirs when planning and optimizing polymer flooding technologies in oil production problems. Three-dimensional hydrodynamic modeling is performed taking into account that the viscosity of the displacing agent in the reservoir is calculated according to a tabularly specified dependence on the polymer concentration and shear rate. The paper presents the results of computational experiments for polymer flooding for a three-dimensional reservoir model with and without taking into account the shear rate for two types of oil and polymers. Evaluations of the polymer flooding efficiency are given. It is shown that the bottomhole pressure significantly depends on the shear rate. Therefore, failure to take into account the shear rate during planning may lead to incorrect conclusions about possible daily volumes and concentrations of polymer injection, incorrect predictions of bottomhole pressures, and also lead to significant distortions in the assessment of the effectiveness of polymer flooding as a whole.
