An automated well bore compensation control system including an oil well, a pump pumping heavy oil from the oil well and at least one sensor monitoring selected pump parameters. A tank is provided containing diluents and a diluents flow line, having flow controls, extends from the tank to the oil well. A controller receives data from the sensor and operates the flow controls to provide diluents to the oil well when the selected pump parameters are not within pre-selected operating limits.
Il s'agit d'un système de commande de compensation de puits de forage automatisé qui comprend un puits de pétrole, une pompe pompant le pétrole brut lourd du puits de pétrole et au moins un capteur contrôlant les paramètres de pompe sélectionnés. Un réservoir, qui contient des diluants et une conduite d'écoulement de diluants, ayant des commandes d'écoulement, va du réservoir jusqu'au puits de pétrole. Un contrôleur reçoit des données du capteur et déclenche les commandes d'écoulement pour fournir des diluants au puits de pétrole lorsque les paramètres de pompe sélectionnés ne sont pas dans les limites de service présélectionnées.
