Abstract

Cette invention concerne un système destiné à actionner de manière sélective plusieurs dispositifs de charge, tel que des outils de puits, qui sont actionnés de manière sélective par application d'une tension prédéterminée aux bornes d'une paire prédéterminée de conducteurs. Au moins un système de verrouillage est associé à chaque dispositif de charge. Le système de verrouillage empêche le courant de parcourir le dispositif de charge respectif jusqu'à ce que la tension aux bornes de la paire de conducteurs dépasse un minimum prédéterminé. L'invention concerne un procédé permettant de sélectionner des outils de puits à actionner par application d'une tension minimale aux bornes d'un ensemble de conducteurs et un système de verrouillage. Les systèmes de verrouillage empêchent le courant de s'échapper par les trajets cachés. Le système est conçu pour appliquer un courant à des dispositifs de charge bidirectionnels tels que des pompes et des moteurs de fonds de puits.
