A control module system provides convenient and economical operation of downhole tools, which operation is controllable from a remote location. In a described embodiment, a control module system includes a control circuit configured to control selective opening of a plurality of valves interconnected between a plurality of accumulators and multiple tools, all positioned within the well. Additionally, the control circuit communicates with a terminal at the earth's surface for transmitting instructions from the terminal to the control circuit, and for transmitting data from the control circuit to the terminal.

La présente invention a pour objet un module de commande permettant de commander à distance, de façon pratique et économique, le fonctionnement d'outils de forage fond de trou à partir d'un emplacement éloigné. Une des versions détaillées de l'invention comporte un module de commande avec circuit de commande configuré pour contrôler l'ouverture sélective d'une pluralité de valves en interconnexion, situées entre une pluralité d'accumulateurs et d'outils multiples, le tout étant logé à l'intérieur du puits. Par ailleurs, le circuit de commande est en communication avec un terminal de surface aux fins de transmission d'instructions entre le terminal et le circuit de commande, et pour la transmission de données entre le circuit de commande et le terminal.
