Abstract: front page image
(EN)An impact dissipation tool for supporting a downhole tool in downhole applications. The tool includes a base and a housing. The tool also includes a carriage located within the housing and coupled to the base, the carriage being movable relative to the housing upon a predetermined impact force. A dissipator disposed inside the housing is collapsible due to the relative movement of the carriage and the housing. The collapse of the dissipator dissipates the impact force transferred to the downhole tool.
(FR)Outil de dissipation de chocs destiné à supporter un outil de fond de trou lors d'applications de fond de trou. L'outil comprend une base et un logement. L'outil comprend également un chariot situé dans le logement et accouplé à la base, le chariot étant mobile par rapport au logement lors d'une force de choc prédéfinie. Un dissipateur disposé à l'intérieur du logement est pliable en raison du déplacement relatif du chariot et du logement. Le pliage du dissipateur dissipe la force de choc transférée à l'outil de fond de trou.
