CA 2401791

A petroleum well (20) for producing petroleum products that incorporates a system adapted to controllably route communications and/or electrical power having a time-varying current through a piping structure (30 and/or 40) in the well (20), and methods of producing petroleum products use such a well, are provided by the present invention. The system comprises a first induction choke (70 or 100), a second induction choke (70 or 100), and a controllable switch (90). The first induction choke (70 or 100) is located about a portion of a first branch (26) of the piping structure (30 and/or 40). The second induction choke (70 or 100) is located about a portion of a second branch (29) of the piping structure (30 and/or 40). The controllable switch (90) comprises two switch terminals. A first of the switch terminals is electrically connected to the piping structure (30 and/or 40) on a junction side (81) of the induction chokes (70 or 100). The first and second branches (26 and 29) of the piping structure (30 and/or 40) intersect on the junction side (81) of the induction chokes (70 or 100). A second of the switch terminals is electrically connected to the piping structure (30 and/or 40) on another side (82) of at least one of the induction chokes (70 or 100).

L'invention concerne un puits de pétrole (20) destiné à la production de produits pétroliers, qui comprend un système conçu pour acheminer de manière contrôlée des communications et/ou de l'énergie électrique dotée d'un courant variant dans le temps à travers une structure de canalisations (30 et/ou 40) dans le puits (20). L'invention concerne également des procédés de production de produits pétroliers au moyen dudit puits de pétrole. Le système comporte une première duse d'induction (70 ou 100), une seconde duse d'induction (70 ou 100) et un commutateur à commande (90). La première duse d'induction (70 ou 100) est située autour d'une partie d'une première branche (26) de la structure de canalisations (30 et/ou 40) et la seconde duse d'induction (70 ou 100) est située autour d'une partie d'une seconde branche (29) de la structure de canalisations (30 et/ou 40). Le commutateur à commande (90) comporte deux terminaux. Le premier terminal est connecté électriquement à la structure de canalisation (30 et/ou 40) d'un côté raccordement (81) des duses d'induction (70 ou 100). La première et la seconde branche (26 et 29) de la structure de canalisation (30 et/ou 40) se croisent du côté raccordement (81) des duses d'induction (70 ou 100). Le second terminal est connecté électriquement à la structure de canalisation (30 et/ou 40) d'un autre côté (82) d'au moins une des duses d'induction (70 ou 100).
