Abstract

Представлен способ разрыва подземной формации, в котором инертный маскирующий материал нагнетается в формацию с растворяющим агентом так, что маскирующий материал замедляет растворение там, где он контактирует с частью одной или обеих поверхностей разрыва. Нерастворенные области обеспечивают поддержку для удержания разрыва открытым после обработки, и растворенные области обеспечивают проводящие протоки для течения флюида в или из скважины.
