Abstract

Настоящее изобретение касается способов интенсификации добычи углеводородов из подземного пласта (40). Согласно настоящему изобретению описываются способы увеличения отбора жидкости для гидравлического разрыва пласта из трещины (42), намеренно созданной в пласте (40), посредством чего увеличивается эффективная длина трещины (42) и, тем самым, повышается добыча углеводородов. Способы согласно настоящему изобретению включают в себя составление графиков использования десгустителей с их постадийным изменением, так что жидкость вблизи оконечности (46) трещины (42) первой понижает свою вязкость, создавая градиент вязкости, который вызывает движение жидкости, находящейся в оконечности (46) трещины, по направлению к стволу скважины (10), где она может быть легче удалена. Предпочтительные варианты воплощения изобретения включают в себя использование газа для вспенивания жидкости на ранних стадиях закачивания для создания градиента плотности, а также использование волокнистого материала на поздних стадиях закачивания для стабилизации набивки из расклинивающего агента.Международная заявка была опубликована вместе с отчетом о международном поиске.
