Title
(EN) PRESSURE TESTING VALVE AND METHOD OF USING THE SAME
(FR) SOUPAPE DE CONTRÔLE DE PRESSION ET PROCÉDÉ D'UTILISATION ASSOCIÉ
Abstract
(EN) A wellbore system comprising a casing, and a pressure testing valve (100) incorporated within the casing and comprising a sleeve (126) positioned within a housing (120) and transitional from a first to a second position, and from the second to a third position, wherein, when the sleeve is in the first and second positions, the sleeve blocks a route of fluid communication via one or more housing ports (122) and, when the sleeve is in the third position the sleeve does not block fluid communication, wherein the pressure testing valve is configured such that a force in the direction of the second position to the sleeve causes the sleeve to transition to the second position, and wherein the pressure testing valve is configured such that a reduction of the force in the direction of the second position to the sleeve causes the sleeve to transition to the third position.
(FR) L'invention concerne un système de trou de forage comprenant un carter et une soupape de contrôle de pression incorporée à l'intérieur du carter et comprenant un manchon positionné à l'intérieur d'un logement et pouvant passer d'une première à une deuxième position et de la deuxième position à une troisième position, selon lequel, lorsque le manchon est dans les première et deuxième positions, le manchon bloque une voie de communication fluidique par le biais d'un ou de plusieurs orifices de logement et, lorsque le manchon est dans la troisième position, le manchon ne bloque pas la communication fluidique, la soupape de contrôle de pression étant conçue de sorte qu'une force dans la direction de la deuxième position vers le manchon amène le manchon à passer dans la deuxième position, et la soupape de contrôle de pression étant conçue de sorte qu'une réduction de la force dans la direction de la deuxième position vers le manchon amène le manchon à passer dans la troisième position.
