Abstract

Le groupe d'inventions se rapporte à la mise en valeur de gisements sous-marins de produits d'extraction liquides et/ou gazeux. Le procédé consiste à monter au-dessus de a source d'écoulement un dispositif comprenant un récipient divisé par un piston mobile commandé en des chambres à volume variables pour le fluide de travail et les produits d'extraction. Les produits d'extraction liquides ou gazeux sont envoyés dan la chambre pour les produits extraction; pendant le remplissage de cette dernière le piston se déplace librement sous la pression des produits d'extraction ou est commandé pour se déplacer dans le sens de la chambre pour le fluide de travail et chasse le fluide de travail hors cette chambre. On effectue ensuite le prélèvement des produits d'extraction au moyen de réservoir que l'on raccorde périodiquement aux orifices disposés en dessous du niveau du piston de séparation. Le résultat technique consiste en une meilleure efficacité d'extraction sous-marine d'hydrocarbures
