Title (EN) SYSTEM AND METHOD FOR PROVIDING A DOWNHOLE MECHANICAL ENERGY ABSORBER
(FR) SYSTÈME ET PROCÉDÉ POUR FOURNIR UN ABSORBEUR D'ÉNERGIE MÉCANIQUE DE FOND DE TROU
Abstract: front page image
(EN)A system and a method are disclosed for providing a downhole mechanical energy absorber (2, 3, 5, 7) that protects downhole tools from impact loads and shock loads that occur during run-in contacts, tool drops, perforating blasts, and other impact events. A continuous localized inelastic deformation of a tube 5 is a primary energy absorber in a load limiting design of the downhole mechanical energy absorber (2, 3, 5, 7).
(FR)L'invention porte sur un système et sur un procédé pour fournir un absorbeur d'énergie mécanique de fond de trou (2, 3, 5, 7) qui protège des outils de fond de trou de charges d'impact et de charges de choc qui se produisent lors de contacts de descente, de chutes d'outil, d'explosions de perforation et autres événements d'impact. Une déformation inélastique localisée continue d'un tube est un absorbeur d'énergie primaire dans une conception de limitation de charge de l'absorbeur d'énergie mécanique de fond de trou (2, 3, 5, 7).
