Patent

CA 2278466

A microprocessor-based controller (200) for oil or gas wells using a plunger lift device (22) is disclosed, which responds to variations in the well production and operation through a series of pressure input signals derived from the well operation. The controller (200) will automatically make corrections in the operation cycles to maximize the well performance and maintain environmental safety.

On décrit un dispositif de contrôle (200) commandé par microprocesseur destiné à des puits de pétrole ou de gaz qui comprend un piston plongeur (22) et qui réagit aux variations se produisant dans le fonctionnement et la production du puits communiquées par une série de signaux d'entrée de pression provenant du puits en fonctionnement. Le dispositif de contrôle (200) effectue automatiquement les corrections relatives aux cycles de fonctionnement pour accroître au maximum la productivité du puits et pour maintenir la sécurité environnementale.
