Трехмерное гидродинамическое моделирование выполняется с учетом того, что вязкость вытесняющего агента в пласте вычисляется по таблично заданной зависимости ее от концентрации полимера и скорости сдвига. В работе представлены результаты вычислительных экспериментов при проведении полимерного заводнения для трехмерной модели пласта с учетом и без учета скорости сдвига для двух типов нефти и полимеров. Даны оценки эффективности полимерного заводнения. Показано, что от скорости сдвига существенно зависит забойное давление. Поэтому неучет скорости сдвига при планировании может повлечь неправильные выводы о возможных суточных объемах и концентрациях закачки полимера, неверные прогнозы забойных давлений, а также приводить к существенным искажениям оценки эффективности полимерного заводнения в целом.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полимерное заводнение</kwd><kwd>гидродинамическое 3D-моделирование</kwd><kwd>скорость сдвига</kwd><kwd>многофазный многокомпонентный поток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymer flooding</kwd><kwd>3D hydrodynamic modeling</kwd><kwd>shear rate</kwd><kwd>multiphase multicomponent flow</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Александров В.М., Закиров Н.Н., Телегин И.Г., Закиров Р.Н.
