Title
(EN) DEVICE FOR IMPROVING OIL AND GAS RECOVERY IN WELLS
(FR) DISPOSITIF SERVANT À AMÉLIORER LA RÉCUPÉRATION DE PÉTROLE ET DE GAZ DANS UN PUITS
Abstract
(EN)
A device for improving recovery of hydrocarbons through a well by creating, regulating and maintaining under the device a calculated bottomhole pressure at a desired level and creating above the device a two-phase gas-liquid homogenous flow for efficient lifting of hydrocarbons to a surface, the device has a body having a central through-going opening with a shape corresponding a shape of a laval nozzle and with a cross section which changes steplessly and gradually, and a mandrel attachable to a tubing and associated with the body without interfering with a flow of fluids.
(FR)
La présente invention concerne un dispositif visant à améliorer la récupération des hydrocarbures dans un puits au moyen d'un dispositif permettant de créer, de réguler et de maintenir une pression au fond du puits calculée au niveau souhaité, et à créer, au-dessus dudit dispositif, un débit homogène gaz-liquide biphasé permettant de remonter efficacement les hydrocarbures jusqu'à la surface. Le dispositif est constitué d'un corps muni d'une ouverture le traversant, dont la forme correspond à celle d'une tuyère de Laval dont la section transversale change en continu et graduellement ainsi que d'un mandrin que l'on peut raccorder à un tube et relier au corps du dispositif sans interférence avec le débit de liquides.
