Abstract
Раскрыта система, предназначенная для уплотнения кольцевого пространства между трубчатым элементом (7), продолжающимся внутрь скважины (1), и цилиндрической стенкой (1b), окружающей трубчатый элемент, в которой линия (18) управления, предназначенная для управления скважинным устройством (12, 13, 14, 15), продолжается в продольном направлении вдоль трубчатого элемента. Система содержит кольцевой уплотнительный слой (20), продолжающийся вокруг трубчатого элемента (7), причем уплотнительный слой имеет внутреннюю поверхность, выполненную с выемкой (40), для радиальной установки в нее линии управления. Уплотнительный слой содержит продольный разрез (31), образующий пару противоположных продольных кромок (32, 34), которые можно перемещать относительно друг друга между открытым положением, в котором уплотнительный слой можно радиально устанавливать на трубчатый элемент, и закрытым положением, в котором уплотнительный слой продолжается вокруг трубчатого элемента.A system is disclosed for sealing the annular space between a tubular element (7) extending into the well (1) and a cylindrical wall (1b) surrounding the tubular element, in which a control line (18) for controlling the downhole device (12, 13) , 14, 15), continues in the longitudinal direction along the tubular element. The system contains an annular sealing layer (20) extending around the tubular element (7), wherein the sealing layer has an inner surface made with a recess (40) for radially installing the control line therein. The sealing layer comprises a longitudinal cut (31) defining a pair of opposing longitudinal edges (32, 34) that can be moved relative to each other between an open position in which the sealing layer can be radially mounted on the tubular element and a closed position in which the sealing layer continues around the tubular element.
