CA 2685955

A power transmission system for use with downhole equipment in a borehole, comprising a power source positioned at the surface providing a DC power supply and a downhole DC/DC converter, connected to the power source by a two-conductor cable and which takes the DC voltage supply as an input and provides an output DC supply at a different voltage to the DC power supply for provision to the downhole equipment.

L'invention concerne un système de transmission de puissance pour une utilisation avec un équipement d'extraction dans un trou de forage, comportant une source d'alimentation positionnée à la surface fournissant une alimentation électrique en courant continu et un convertisseur courant continu/courant continu de fond de puits, connecté à la source d'alimentation par un câble à deux conducteurs et qui prend l'alimentation de tension en courant continu comme entrée et fournit une alimentation en courant continu de sortie à une tension différente à l'alimentation électrique en courant continu pour alimenter l'équipement d'extraction.
