A signal transmission device transmits power and / or data between one or more surface devices and one or more downhole devices positioned in a wellbore. The signal transmission device includes at least one conductive element that electrically couples to one or more downhole devices and electrically couples at a surface end to the one or more surface devices. The conductive element is also coupled to the wellbore tubular to form a conductive circuit. The conductive element can also include a bore for conveying fluid from a surface source.
Selon l'invention, un dispositif de transmission de signal transmet du courant et/ou des données entre un ou plusieurs dispositifs de surface et ou un plusieurs dispositifs de fond positionnés dans un puits de forage. Le dispositif de transmission de signal comprend au moins un élément conducteur qui est raccordé électriquement à ou aux dispositifs de fond et au niveau d'une extrémité de surface à ou aux dispositifs de surface. L'élément conducteur est également raccordé aux tubes du puits de forage afin que soit formé un circuit conducteur. L'élément conducteur peut également comprendre un trou de forage pour transporter un fluide depuis une source de surface.
