Title
(EN) VALVE WITH INTEGRATED FLUID RESERVOIR
(FR) VANNE À RÉSERVOIR DE FLUIDE INTÉGRÉ
Abstract
(EN)
Certain aspects and features of the disclosure relate to a valve device for use in a wellbore. In one example, the valve device includes a body containing swell fluid, a swellable elastomer, and a piston. The swell fluid can contact the swellable elastomer, causing the swellable elastomer to swell. The swellable elastomer can swell and contact the piston. The swellable elastomer can move the piston from a first position to a second position. In the second position, the piston can open, close, or restrict one or more flow paths through the valve device.

Certains aspects et caractéristiques de l'invention concernent un dispositif à vanne destiné à être utilisé dans un puits de forage. Dans un exemple, le dispositif à vanne comprend un corps contenant un fluide de gonflage, un élastomère gonflable et un piston. Le fluide de gonflage peut entrer en contact avec l'élastomère gonflable, ce qui fait gonfler l'élastomère gonflable. L'élastomère gonflable peut gonfler et entrer en contact avec le piston. L'élastomère gonflable peut déplacer le piston d'une première à une seconde position. Dans la seconde position, le piston peut ouvrir, fermer ou restreindre un ou plusieurs trajets d'écoulement à travers le dispositif à vanne.
