Abstract

Скважинный инструмент содержит корпус инструмента, содержащий внутренний корпус и наружный корпус, которые образуют кольцевое пространство между внутренним корпусом и наружным корпусом, и основной поршень, расположенный внутри кольцевого пространства, образующий основную полость внутри кольцевого пространства. Скважинный инструмент дополнительно содержит дублирующий поршень, расположенный внутри кольцевого пространства, образующий вторую внутреннюю полость внутри кольцевого пространства, и устройство для регулирования давления, гидравлически соединенное с кольцевым пространством.
