Title
(EN) METHOD AND APPARATUS FOR PRODUCING WELL WITH BACKUP GAS LIFT AND AN ELECTRICAL SUBMERSIBLE WELL PUMP
(FR) PROCÉDÉ ET APPAREIL POUR PRODUIRE UN PUITS AVEC UN ÉLÉVATEUR DE GAZ DE SECOURS ET UNE POMPE DE PUITS SUBMERSIBLE ÉLECTRIQUE
Abstract
(EN)
A well production method uses side gas lift valves (45) above a packer (29) and an ESP (13) below the packer. In a gas lift mode, a controller (26) turns the ESP motor (15) off, and shifts a tubing valve (39) below the packer (29) to a gas lift position while flowing gas down the casing (11). While in the gas lift mode, a pressure gauge (25) monitors motor lubricant pressure, which correlates with a flowing bottom hole pressure of the well fluid in the lower casing annulus (35). In an ESP mode, the controller (26) stops the flow of gas from the gas source, shifts the tubing valve (39) to an ESP position and turns on the motor (15), causing well fluid to flow through the pump intake (20). The pressure gauge (25) continues to monitor the lubricant pressure during the ESP mode.
(FR)
La présente invention concerne un procédé de production de puits qui utilise des soupapes d'élévation de gaz latérales (45) au-dessus d'une garniture d'étanchéité (29) et un ESP (13) au-dessous de la garniture d'étanchéité. Dans un mode d'élévation de gaz, un dispositif de commande (26) désactive le moteur ESP (15) et décale une vanne de colonne de production (39) sous la garniture d'étanchéité (29) vers une position d'élévation de gaz, tout en faisant circuler le gaz vers le bas du boîtier (11). En mode d'élévation de gaz, une jauge de pression (25) surveille la pression de lubrifiant de moteur, qui est en corrélation avec une pression d'écoulement de fond de trou du fluide de puits dans l'espace annulaire de boîtier inférieur (35). Dans un mode ESP, le dispositif de commande (26) arrête l'écoulement de gaz provenant de la source de gaz, décale la vanne de colonne de production (39) vers une position d'ESP et active le moteur (15), amenant le fluide de puits à s'écouler à travers l'admission de pompe (20). La jauge de pression (25) continue à surveiller la pression de lubrifiant pendant le mode ESP.
