Abstract

Приводятся способы и системы для повышения извлечения углеводородов из пласта путем изменения смачиваемости поверхности пласта в сторону большей гидрофильности. Один из способов включает в себя подготовку пласта; подготовку водного потока для закачивания в пласт; добавление восстановителя в водный поток; и закачивание водного потока с восстановителем в пласт для изменения заряда поверхности на поверхности пласта в сторону большей гидрофильности для повышения извлечения углеводородов из пласта. Восстановитель реагирует на характеристики пласта, характеристики солевого раствора пласта и характеристики углеводородов пласта. Также приводится способ для выбора состава закачиваемого в пласт солевого раствора для изменения смачиваемости поверхности пласта в сторону большей гидрофильности для повышения извлечения углеводородов из пласта.
