Title
(EN) ISOLATION VALVE FOR SUBTERRANEAN USE
(FR) VANNE D'ISOLATION À USAGE SOUTERRAIN
Abstract
(EN)
A valve on an inner string can only be closed with multiple movements in opposed directions that occur after a predetermined force is held for a finite time. Holding the force against resistance eventually allows movement that arms the valve. A set down and pickup force will then close the valve. The surrounding string has a constriction that interacts with a j-slot to rotate a wedge with a first peak into alignment with a peak on a second wedge that can only translate against a spring bias. The second wedge is eccentrically linked to a ball that rotates between and open and a closed position.
(FR)
Une vanne sur un tubage de production ne peut se fermer que par plusieurs mouvements dans des directions opposées, ceux-ci s'effectuant après maintien d'une force prédéterminée sur une durée limitée. Le maintien de la force contre la résistance permet éventuellement le mouvement qui déclenche la vanne. Une force de pose et de prélèvement fermera alors la vanne. Le tubage environnant présente un étranglement qui a une interaction avec une fente en j de façon à faire tourner un coin par rapport à une première crête en alignement avec une crête d'un second coin qui ne peut translater que par rapport à la sollicitation d'un ressort. Le second coin est relié de manière excentrique à une bille qui tourne entre une position ouverte et une position fermée.
