Abstract

Скважинный инструмент (10) для изоляции формации в стволе скважины от давления текучей среды, введенной с поверхности. Будучи установленным в спусковую колонну, инструмент обеспечивает осевой сквозной канал (18) и радиальные выходы (40, 42) над и под постоянным уплотнительным элементом (26), таким как отводная манжета. Клапанные элементы (44, 50), которые могут представлять собой втулки, расположенные внутри осевой скважины, управляются путем активации через спусковую колонну для последовательного движения, так что первый путь циркуляции создается вокруг уплотнения через радиальные выходы и независимо от осевой сквозной скважины, осевой сквозной канал блокируется и создается второй путь циркуляции между осевым каналом и верхним радиальным выходом, и поток через осевой канал восстанавливается, в то же время сохраняя второй путь потока.
