Abstract

L'invention se rapporte au domaine des techniques de pompage par jet pour des puits. Sur un tube flexible et lisse (1) sont montés un dispositif de carottage (2), un élément d'étanchéité (3) et une pompe à jets (4). Le corps (5) de la pompe (4) comprend une buse (6) et une chambre de mélange (7) avec un diffuseur (8). La sortie du diffuseur (8) est connectée à la cavité du tube (1), et l'entrée de la buse (6) est connectée à l'espace extérieur au tube (1). Des clapets anti-retour (10, 24) sont montés sur les entrées du canal (9) d'alimentation en milieu de pompage et sur la buse (6). Le tube (1) est capable de se déplacer dans le train de tiges de pompage et de compression (11) qui comporte un packer (12). Le diamètre D1 du canal d'écoulement du packer (12) est inférieur d'au moins 12 mm au diamètre interne D2 des tubes (12). Des ouvertures (14) sont formées dans le tube (1) au-dessus du dispositif (2). Une vanne à bille (23) permettant de fermer le tube (1) est montée sur le tube (1) entre la pompe (4) et l'élément (3). L'élément (3) se présente sous forme d'un corps cylindrique (15) rempli d'un ensemble de joints élastiques (16) comportant des rondelles de pression (17) et un élément de pression compressible (18) sur le haut. En dessous du corps (15) est fixé un insert (19) comportant un flanc (20) et un anneau mobile (21), un manchon (22) étant disposé entre ces derniers et le corps (15). Le diamètre du flanc (20) est inférieur au diamètre D1 du canal d'écoulement du packer (12). L'anneau (21) possède un diamètre D3 supérieur au diamètre D1. La surface inférieure de l'anneau (21) est recouverte d'un matériau élastique. On obtient ainsi une amélioration de la fiabilité de fonctionnement de cette installation.
