Title (EN) METHOD OF SELECTIVE PLASTIC EXPANSION OF SECTIONS OF A TUBING
(FR) PROCEDE DE DILATATION PLASTIQUE SELECTIVE DE SECTIONS D'UN TUBE
Abstract: front page image
(EN)A method of selective plastic expansion of sections of a tubing to create one or more recesses in the tubing with a larger diameter than that of the original tubing in which the tubing is radially symmetrically or asymmetrically expanded at one or more locations by application of a radial force to the interior of the tubing thereby inducing a plastic radial deformation of the tubing and removing said radial force from the interior of the tubing. The tubing can be a downhole tubing and the created recesses are preferably utilized to hold at least one downhole device, which is advantageously a gas lift mandrel or a sensor.
(FR)L'invention concerne un procédé de dilatation plastique sélective de sections d'un tube permettant de créer un ou plusieurs évidements dans ledit tube, d'où un diamètre plus large que celui du tube original. On dilate radialement le tube de manière symétrique ou asymétrique en un ou plusieurs emplacements en appliquant une force radiale vers l'intérieur du tube, provoquant ainsi une déformation plastique radiale du tube, puis on supprime la force radiale exercée vers l'intérieur du tube. Le tube peut être un tube de fond de puits, et lesdits évidements sont utilisés de préférence pour retenir au moins un dispositif de fond de puits, et notamment un mandrin de gas-lift ou un capteur.
