Title
(EN) OPTICAL CASING COLLAR LOCATOR SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTEUR DE JOINT DE TUBAGE OPTIQUES
Abstract
(EN)
Disclosed are fiber optic enabled casing collar locator systems including a wireline sonde or a coil tubing sonde apparatus configured to be conveyed through a casing string by a fiber optic cable. The sonde includes at least one permanent magnet producing a magnetic field that changes in response to passing a collar in the casing string, a coil that receives at least a portion of the magnetic field and provides an electrical signal in response to the changes in the magnetic field, and a light source that responds to the electrical signal to communicate light along an optical fiber to indicate passing collars. Methods for using the sonde to locate casing collars in the casing string are also described.

L'invention concerne des systèmes de détecteur de joint de tubage équipés de fibre optique comprenant un appareil à sonde à câble métallique ou à sonde à tube spiralé conçu pour être transporté à travers une colonne de tubage par un câble de fibre optique. La sonde comprend au moins un aimant permanent produisant un champ magnétique qui change en réponse au passage d'un joint dans la colonne de tubage, une bobine qui reçoit au moins une partie du champ magnétique et produit un signal électrique en réponse aux changements dans le champ magnétique, et une source de lumière qui répond au signal électrique pour communiquer la lumière le long d'une fibre optique pour indiquer le passage des joints. L'invention concerne aussi des procédés pour utiliser la sonde pour détecter les joints de tubage dans la colonne de tubage.
