Abstract
Cette invention se rapporte à une purge de conduits de fibres optiques dans des puits souterrains. Un système de détection optique de fond de trou comprend une ligne optique, au moins deux conduits tubulaires, un conduit étant positionné à l'intérieur de l'autre conduit, et la ligne optique étant positionnée à l'intérieur d'un ou des deux conduits, et un milieu de purge qui circule dans une direction à travers un conduit, et qui circule dans la direction opposée entre les conduits. Un procédé de purge d'un système de détection optique de fond de trou comprend les étapes consistant à : installer au moins deux conduits et une ligne optique dans un puits en tant qu'élément du système de détection, un conduit étant positionné à l'intérieur de l'autre conduit, et la ligne optique étant positionnée à l'intérieur d'un ou des deux conduits; et faire circuler un milieu de purge à travers les conduits dans le puits, de telle sorte que le milieu de purge circule dans une direction à travers un conduit et dans une direction opposée entre les conduits.
