Title (EN) METHOD AND APPARATUS FOR SEALING AN ANNULUS AROUND A DRILL-PIPE WHEN DRILLING DOWN-HOLE
(FR) PROCÉDÉ ET APPAREIL POUR SCELLER UN ESPACE ANNULAIRE AUTOUR D'UN TUYAU DE FORAGE LORS D'UN FORAGE DE FOND DE TROU
Abstract: front page image
(EN)A method of sealing an annulus around a drill-pipe when drilling down-hole comprises: providing a deflated packer on a drill-pipe when drilling down-hole; opening one or more ports to the packer using a ball-activated valve; and circulating drilling fluid to inflate said packer through said one or more ports, to thereby form a seal in the annulus around the drill-pipe. An apparatus to carry out this method is also provided.
(FR)L'invention concerne un procédé de scellage d'un espace annulaire autour d'un tuyau de forage lors d'un forage de fond de trou, comprenant : la fourniture d'une garniture d'étanchéité dégonflée sur un tuyau de forage lors d'un forage de fond de trou ; l'ouverture d'un ou plusieurs orifices sur la garniture d'étanchéité au moyen d'une soupape activée par bille ; et la circulation de fluide de forage pour gonfler ladite garniture d'étanchéité par le biais desdits un ou plusieurs orifices, pour former de ce fait un joint dans l'espace annulaire autour du tuyau de forage. L'invention concerne également un appareil pour effectuer ce procédé.
