Title (EN) BACK PRESSURE VALVE FOR A COMPLETION STRING COMPRISING SAND SCREENS, COMPLETION STRING COMPRISING SAID BACK PRESSURE VALVE, AND METHOD FOR LOWERING SAID COMPLETION STRING
(FR) SOUPAPE DE CONTRE-PRESSION DESTINÉE À UNE COLONNE DE COMPLÉTION COMPRENANT DES TAMIS À SABLE, COLONNE DE COMPLÉTION COMPRENANT LADITE SOUPAPE DE CONTRE-PRESSION, ET PROCÉDÉ D'ABAISSEMENT DE LADITE COLONNE DE COMPLÉTION
Abstract: front page image
(EN)Herein is described a back pressure valve ( 1) for a completion string (10) comprising sand screens (101), the back pressure valve (1) comprising: - a valve body (2); - a valve seat (7); - a valve head (8) for sealing against the valve seat (7); - a valve stem (4) connected to the valve head (8) for guiding the valve head (8); and - a resilient member (9) arranged around a portion of the valve stem (4); wherein the valve stem (4) is guided by at least two supports (13, 15) which are spaced apart in the longitudinal direction of the valve stem (4), the at least two supports (13, 15) being configured for allowing translation of the valve stem (4) in its longitudinal direction only. Furthermore, a method for using said back pressure valve (1) is described, wherein the method comprises the step of providing the back pressure valve (1) in a completion string.
(FR)La présente invention concerne une soupape de contre-pression (1) destinée une colonne de complétion (10) comprenant des tamis à sable (101), la soupape de contre-pression (1) comprenant : - un corps (2) de soupape ; - un siège (7) de soupape ; - une tête (8) de soupape destinée à assurer l'étanchéité du siège (7) de soupape ; - une tige (4) de soupape, reliée à la tête (8) de soupape, destinée à guider la tête (8) de soupape ; et - un élément élastique (9) disposé autour d'une partie de la tige (4) de soupape ; la tige (4) de soupape étant guidée par au moins deux supports (13, 15) qui sont espacés l'un de l'autre dans la direction longitudinale de la tige (4) de soupape, lesdits supports (13, 15) étant conçus pour permettre la translation de la tige (4) de soupape dans sa direction longitudinale uniquement. De plus, l'invention concerne un procédé d'utilisation de ladite soupape de contre-pression (1), le procédé comprenant l'étape consistant à utiliser la soupape de contre-pression (1) dans une colonne de complétion.
