Title
(EN) HEATERS TO ACCELERATE SETTING OF EXPANDABLE METAL
(FR) DISPOSITIFS DE CHAUFFAGE POUR ACCÉLÉRER LA MISE EN PLACE D'UN MÉTAL EXPANSIBLE
Abstract
(EN)
Provided is a method for setting a downhole tool, and a downhole localized heater. The method, in at least one aspect, includes positioning a downhole tool within a wellbore, the downhole tool including expandable metal configured to expand in response to hydrolysis, and positioning a downhole localized heater within the wellbore, the downhole localized heater being proximate the expandable metal. The method additionally includes subjecting the expandable metal to a wellbore fluid to expand the expandable metal into contact with one or more surfaces while activating the downhole localized heater to create a temperature spike and accelerate an expansion of the expandable metal.

L'invention concerne un procédé de réglage d'un outil de fond de trou, et un dispositif de chauffage localisé de fond de trou. Le procédé, dans au moins un aspect, comprend le positionnement d'un outil de fond de trou à l'intérieur d'un puits de forage, l'outil de fond de trou comprenant un métal expansible conçu pour se dilater en réponse à l'hydrolyse, et le positionnement d'un dispositif de chauffage localisé de fond de trou à l'intérieur du puits de forage, le dispositif de chauffage localisé de fond de trou étant à proximité du métal expansible. Le procédé comprend en outre la soumission du métal expansible à un fluide de puits de forage pour dilater le métal expansible en contact avec une ou plusieurs surfaces tout en activant le dispositif de chauffage localisé de fond de trou pour créer un pic de température et accélérer une expansion du métal expansible.
