Title (EN) IMPROVED GAS LIFT SYSTEM FOR OIL PRODUCTION
(FR) SYSTÈME AMÉLIORÉ D'EXTRACTION AU GAZ POUR LA PRODUCTION DE PÉTROLE
Abstract: front page image
(EN)An improved gas lift system for use in oil production from a well bore (11) utilising a gas lift injection (10) system of the known type and further including a surface jet pump (16) downstream of the well head (13) for reducing the flowing well head pressure and capable of discharging produced fluid (14) at a pressure required by a downstream production system.
(FR)L'invention concerne un système amélioré d'extraction au gaz à utiliser dans la production de pétrole à partir d'un puits de forage (11) utilisant un système d'injection d'extraction au gaz (10) du type connu et comprenant de plus une pompe à jet de surface (16) en aval de la tête de puits (13) qui réduit la pression d'écoulement de la tête de puits et qui est capable d'effectuer le refoulement du fluide produit (14) à une pression nécessaire pour un système de production en aval.
