(FR) ANCRAGE DE TUBAGE AGRANDISSABLE
Abstract:
(EN) A wellbore isolation device includes an expandable housing. The expandable housing has a first end portion and a second end portion. A scarf cut can extend helically about the housing at least partially between the first and second end portions. The scarf cut can have a cut width. The housing is diametrically expandable from a contracted state to an expanded state to set the housing against an inner diameter of a wellbore.
(FR) La présente invention concerne un dispositif d'isolation de puits de forage qui comprend un logement agrandissable. Le logement agrandissable a une première portion d'extrémité et une seconde portion d'extrémité. Une découpe en biseau peut s'étendre de manière hélicoïdale autour du logement au moins partiellement entre les première et seconde portions d'extrémité. La découpe en biseau peut avoir une largeur coupée. Le logement est diamétralement agrandissable d'un état contracté à un état agrandi pour fixer le logement contre un diamètre intérieur d'un puits de forage.
