Abstract
Ci-après, des méthodes et des appareils de communication de fond de trou dans un puits. Le puits possède une structure métallique qui comporte une ligne de commande métallique isolée pour le transport des fluides. La méthode comprend les étapes d'application de signaux à la ligne de commande à un premier emplacement et l'extraction des signaux provenant de la ligne de commande à un deuxième emplacement : on décrit aussi un système de communication de fond de trou à utiliser dans un puits doté d'une structure métallique. La structure métallique comprend une ligne de contrôle métallique isolée pour le transport des fluides. Le système comprend des outils pour l'application de signaux à la ligne de commande à un premier emplacement et l'extraction des signaux provenant de la ligne de commande à un deuxième emplacement : la ligne de commande agit comme un canal de signalisation. D'autres méthodes et appareils utilisant la ligne de commande ne transportant aucun fluide et/ou le blindage métallique du câble sont également décrits.
