Annotation
В работе рассмотрена проблема оценки минимального размера непрорываемой вязкими пальцами оторочки полимерного агента, вытесняющего нефтяной флюид. Выполнено сравнение полученных результатов в пакете ANSYS FLUENT с теоретическими подходами, а также с численным модулем MRST. Осуществлена проверка оптимальности оторочки дополнительными расчетами. Оценено влияние каждого из варьируемых параметров на поведение пальцев и оптимальную толщину оторочки.
The paper considers the problem of estimating the minimum size of a polymer agent slug displacing an oil fluid that cannot be broken by viscous fingers. The results obtained in the ANSYS FLUENT are compared with theoretical approaches, as well as with the numerical software MRST. The optimality of the slug has been verified by additional calculations. The influence of each of the varied parameters on the behavior of the fingers and the optimal thickness of the polymer slug was evaluated.
