Patent

CA 2401707

A petroleum well having a communication system and a hydraulic system is provided. The petroleum well includes a borehole and a piping structure positioned within the borehole. The communication system supplies a time varying electric current downhole along the piping structure. The hydraulic system (70), which is positioned downhole proximate the piping structure (26), receives the time varying current to operate an electric motor (78). The motor drives a pump (76) which pressurizes hydraulic fluid to selectively drive an actuator (84). The actuator (84) is operably connected to a downhole device, such as a shutoff valve, and operates the downhole device as the actuator (84) is driven by the pressurized hydraulic fluid.

L'invention concerne un puits de pétrole comprenant un système de communications et un système hydraulique. Ledit puits de pétrole comprend un trou de forage et une structure de tuyauterie positionnée dans ledit trou de forage. Le système de communications fournit du courant électrique variant dans le temps en fond de puits, le long de la structure de tuyauterie. Le systeme hydraulique (70) placé en fond de puits, à proximité de la structure de tuyauterie (26), reçoit le courant électrique variant dans le temps de façon à activer un moteur electrique (78). Ledit moteur entraîne une pompe (76) qui met le fluide hydraulicque sous pression de façon à entraîner sélectivement un actionneur (84). Ledit actionneur (84) est relié, de manière fonctionnelle, à un dispositif de fond de trou, tel qu'une vanne d'arrêt, et fait fonctionner le dispositif de fond de trou lorsque ledit actionneur (84) est entraîné par le fluide hydraulique sous pression.
