Title
(EN) DOWNHOLE SAND SCREEN WITH AUTOMATIC FLUSHING SYSTEM
(FR) CRIBLE À SABLE DE FOND DE TROU AVEC SYSTÈME DE RINÇAGE AUTOMATIQUE
Abstract
(EN)
A pump that is configured to lift fluids through a tubing string includes a gas mitigation system and a screen flush module. The gas mitigation system has a canister with an interior and an intake screen. The gas mitigation system further includes an intake tube that extends into the canister. The screen flush module is configured to flush solids particles trapped in the intake screen.
(FR)
L'invention concerne une pompe qui est configurée pour élever des fluides à travers une colonne de production et comprend un système d'atténuation de gaz et un module de rinçage de crible. Le système d'atténuation de gaz comprend une cartouche ayant un intérieur et un crible d'admission. Le système d'atténuation de gaz comprend en outre un tube d'admission qui s'étend dans la cartouche. Le module de rinçage de crible est configuré pour rincer les particules solides piégées dans le crible d'admission.
