Title
(EN) RF ANTENNA ASSEMBLY WITH FEED STRUCTURE HAVING DIELECTRIC TUBE AND RELATED METHODS
(FR) ENSEMBLE ANTENNE RF AVEC STRUCTURE D'ALIMENTATION AYANT UN TUBE DIÉLECTRIQUE ET PROCÉDÉS ASSOCIÉS
Abstract
(EN)
An RF antenna assembly may be positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery. The RF antenna assembly includes first and second tubular conductors and a feed structure therebetween defining a dipole antenna to be positioned within the wellbore, and an RF transmission line extending within one of the tubular conductors. The feed structure includes a dielectric tube, a first connector coupling the RF transmission line to the first tubular conductor, and a second connector coupling the RF transmission line to the second tubular conductor.

L'invention porte sur un ensemble antenne RF qui peut être positionné à l'intérieur d'un trou de forage dans une formation souterraine pour une récupération de ressource d'hydrocarbure. L'ensemble antenne RF comprend des premier et second conducteurs tubulaires et une structure d'alimentation entre ceux-ci définissant une antenne dipôle à positionner à l'intérieur du trou de forage, et une ligne d'émission RF s'étendant à l'intérieur de l'un des conducteurs tubulaires. La structure d'alimentation comprend un tube diélectrique, un premier connecteur couplant la ligne d'émission RF au premier conducteur tubulaire, et un second connecteur couplant la ligne d'émission RF au second conducteur tubulaire.
