Zusammenfassung:An assembly adapted to be disposed within an oil or gas wellbore and including first and second completion joints, each including a base pipe, a shunt tube disposed along the base pipe, and a tubular outer shroud disposed about respective portions of the shunt tube and the base pipe; a jumper tube coupling the shunt tube of the first completion joint to the shunt tube of the second completion joint; and a tubular sliding shroud disposed about at least one of the first and second completion joints and adapted to slide longitudinally to a run-in position, in which the tubular sliding shroud is disposed about the jumper tube and respective portions of the first and second completion joints, thereby covering the jumper tube. A method and apparatus are also provided. L'invention concerne un ensemble conçu pour être disposé à l'intérieur d'un puits de forage pour la production de pétrole ou de gaz et comprenant des premier et second raccords de complétion, chacun comprenant un tuyau de base, un tube de dérivation disposé le long du tuyau de base et une enveloppe externe tubulaire disposée autour de parties respectives du tube de dérivation et du tuyau de base ; un tube de pontage raccordant le tube de dérivation du premier raccord de complétion et le tube de dérivation du second raccord de complétion ; et une enveloppe coulissante tubulaire disposée autour d'au moins l'un des premier et second raccords de complétion et conçue pour coulisser longitudinalement vers une position insérée, dans laquelle l'enveloppe coulissante tubulaire est disposée autour du tube de pontage et des parties respectives des premier et second raccords de complétion, ce qui permet de recouvrir le tube de pontage. L'invention concerne également un procédé et un appareil.
