Title
(EN) BATTERY OPERATED AUTONOMOUS SCALE REMOVAL SYSTEM FOR WELLS
(FR) SYSTÈME AUTONOME D'ÉLIMINATION DE DÉPÔT CALCAIRE ALIMENTÉ PAR BATTERIE POUR PUITS
Abstract
(EN)
An autonomously operated well intervention tool system includes a lubricator sealingly affixable to an upper end of a well. The lubricator has a latch at an upper end thereof. A well intervention tool system is releasably matable with the latch. The well intervention tool system comprises a wellbore intervention device at a longitudinal end thereof. The lubricator has at least one isolation valve to close fluid communication between the well and the lubricator.
(FR)
L'invention concerne un système d'outil d'intervention sur puits fonctionnant de façon autonome et comprenant un dispositif de lubrification pouvant être fixé de manière étanche à une extrémité supérieure d'un puits. Le dispositif de lubrification comprend un élément d'enclenchement au niveau d'une extrémité supérieure de celui-ci. Un système d'outil d'intervention sur puits peut s'accoupler de manière amovible avec l'élément d'enclenchement. Le système d'outil d'intervention sur puits comprend un dispositif d'intervention sur puits de forage au niveau d'une extrémité longitudinale de celui-ci. Le dispositif de lubrification comprend au moins une vanne d'isolation destinée à fermer la communication fluide entre le puits et le dispositif de lubrification.
