Patent

CA 2549625

The present invention generally provides apparatuses and methods for an improved shunt nozzle which is part of an alternative pathway for a slurry to by-pass an obstruction such as a sand bridge during gravel packing. In one embodiment, the nozzle has a hardened insert that lines a surface of a hole in the shunt and seats on a surface of a wall proximate the hole, thereby restraining movement of the insert relative to the shunt for welding an outer jacket to the shunt.

Appareils et procédés pour une buse de dérivation améliorée qui fait partie d'une voie alternative permettant à la boue de contourner une obstruction, comme un pont de sable en cours de gravillonnage. Dans un mode de réalisation, la buse comporte une pièce d'insertion durcie qui contacte la surface d'un trou dans l'ouvrage de dérivation et prend appui sur la surface d'une paroi à proximité du trou, ce qui limite le déplacement de la pièce d'insertion par rapport à l'ouvrage de dérivation, auquel une gaine extérieure est soudée.
