Title (EN) A CENTRALIZING AND PROTECTIVE ADAPTER FOR DOWNHOLE TORCH AND METHOD OF USE
(FR) ADAPTATEUR DE PROTECTION ET DE CENTRALISATION DESTINÉ À UNE TORCHE DE FOND DE TROU ET PROCÉDÉ D'UTILISATION
Abstract:
(EN) Apparatus and adapter are usable for aligning downhole torch apparatuses and cutting devices, including axial pyro torches, circulating pyro torches, and radial cutting and perforating torches, within a wellbore for removal of one or more downhole obstructions. The torch and/or cutting apparatus comprises a body having a nozzle adapted to project a fuel load, such as molten thermite or molten thermite with a polymer, in a direction aligned with the obstruction. The adapter comprises protruding elements for eliminating or diminishing damage to the area surrounding the obstruction, including the inner walls of the wellbore and/or casing, and can further comprise centralizers for alignment of the apparatus with the obstruction, within the wellbore.
(FR) L'invention concerne un appareil et un adaptateur utilisables en vue d'aligner des appareils de type torche de fond de trou et des dispositifs de découpe, notamment des torches pyrotechniques axiales, des torches pyrotechniques à circulation, et des torches de découpe et de perforation radiales, à l'intérieur d'un trou de forage afin d'éliminer une ou plusieurs obstructions de fond de trou. La torche et/ou l'appareil de découpe comprennent un corps comportant une buse conçue pour projeter une charge de combustible, tels que de la thermite en fusion ou de la thermite en fusion associée à un polymère, dans une direction alignée avec l'obstruction. L'adaptateur comprend des éléments en saillie servant à éliminer ou à diminuer les dommages provoqués sur la zone circonvoisine à l'obstruction, notamment les parois internes du trou de forage et/ou du tubage, et peut en outre comprendre des éléments centreurs servant à aligner l'appareil par rapport à l'obstruction, à l'intérieur du trou de forage.
