Abstract

Создан скважинный пакер для использования в стволе скважины, и, в частности, пакер, который можно использовать для тестирования скважины. Согласно варианту осуществления изобретения, пакерный инструмент (10) устанавливается на спусковой колонне для обеспечения уплотнения вокруг трубы (32) и содержит корпус (12) с одним или несколькими пакерными элементами (18) и муфтой (14), при этом пакерный инструмент устанавливается путем перемещения муфты относительно корпуса инструмента, вызывающего сжатие одного или нескольких пакерных элементов, и инструмент имеет множество перепускных каналов (16) для обеспечения прохода для текучей среды в обход пакерных элементов к муфте, содержит по меньшей мере один анкерный элемент (22, 50), который активируется для обеспечения контакта с трубой посредством давления текучей среды из перепускных каналов при установке пакера.
