Title (EN) REMOTE PLUGGING DEVICE FOR WELLS
(FR) DISPOSITIF DE COLMATAGE A DISTANCE POUR PUITS
Abstract: front page image
(EN)Remote cement plugging device (10) and method of use. The device has at least one means (60) for perforating at least one hole through a wall of a first well casing, and means to inject cement into an annulus between the inner well casing and a second well casing. The perforating means has at least one punch (65) actuated by compressed fluid (hydraulic, pneumatic) to form the hole(s), and thereafter the cement is delivered to the annulus between the inner and outer/intermediate casings to form the cement plug without the need to withdraw the device from the well casing.
(FR)L’invention concerne un dispositif de colmatage au ciment à distance (10) et son procédé d’utilisation. Le dispositif comprend au moins un moyen (60) servant à percer au moins un trou à travers une paroi d’un premier tubage de puits, et un moyen servant à injecter du ciment dans un espace annulaire entre le premier tubage intérieur de puits et un deuxième tubage de puits. Le moyen de perçage comprend au moins un poinçon (65) actionné par un fluide comprimé (hydraulique, pneumatique) pour former le(s) trou(s). Le ciment est ensuite introduit dans l’espace annulaire entre les tubages intérieur et extérieur/intermédiaire pour former le bouchon de colmatage au ciment sans nécessiter le retrait du dispositif du tubage de puits.
