Abstract

Новая усредненная модель/модель континуума представлена для имитации формирования червоточин в ходе интенсификации добычи из матрицы карбонатов. В усредненной модели, представленной здесь, учитывают физические свойства на уровне пор путем объединения явлений в локальном масштабе пор до макроскопических переменных (скорость Дарси, давление и концентрация чашек реагента-смешения) через взаимозависимость структура-свойство (проницаемость-пористость, средний размер пор-пористость и площадь переходов-пористость) и влияние коэффициента переноса масс флюид-твердое вещество и коэффициента дисперсии текучей фазы на развитие переменных в масштабе пор (средний размер пор, локальное значение чисел Рейнольдса и Шмидта). Эта модель позволяет обеспечить лучшее прогнозирование образования каналов для потока так, что можно проводить регулировку при обработке матрицы для улучшения формирования червоточин.Международная заявка была опубликована вместе с отчетом о международном поиске.
