Abstract | An apparatus, method, and system for determining the propagation delay for a downhole wire and/or for monitoring the integrity of a downhole wire. The apparatus includes a first tool component and a second tool component spaced apart from the first tool component and communicatively coupled by a wire. The tool components include impedance altering devices configured to alter, for a predetermined period of time, either the source impedance at a first termination point of the wire and/or the load impedance at a second termination point of the wire sufficient to generate a characteristic signal reflection upon the transmission of a signal along a length of the wire between the first tool component and the second tool component.
L'invention concerne un appareil, un procédé et un système de détermination du retard de propagation relatif à un fil de fond de trou et/ou de surveillance de l'intégrité d'un fil de fond de trou. L'appareil comprend des premier et second composants d'outil espacés l'un de l'autre et couplés en communication par un fil. Les composants d'outil comprennent des dispositifs de modification d'impédance conçus pour modifier, pendant une période de temps prédéterminée, l'impédance source en un premier point de terminaison du fil et/ou l'impédance de charge en un second point de terminaison du fil d'une manière suffisante pour générer une réflexion de signal caractéristique lors de l'émission d'un signal sur une longueur du fil entre les premier et second composants d'outil. |
