Title (EN) FIXED-WAVELENGTH FIBER OPTIC TELEMETRY FOR CASING COLLAR LOCATOR SIGNALS
(FR) TÉLÉMESURE PAR FIBRE OPTIQUE À LONGUEUR D'ONDE FIXE POUR SIGNAUX DE LOCALISATEUR DE JOINT DE TUBAGE
Abstract:
(EN) A downhole tool, in some embodiments, comprises a casing collar locator (CCL) to generate a signal that indicates the presence of a casing discontinuity; and a modulator, coupled to the CCL, to modulate fixed-wavelength light in a fiber optic cable based on said signal.
(FR) Cette invention concerne un outil de fond de trou, comprenant, selon certains modes de réalisation, un localisateur de joint de tubage (CCL) conçu pour générer un signal indiquant la présence d'une discontinuité de tubage ; et un modulateur, couplé au localisateur de joint de tubage pour moduler une lumière à longueur d'onde fixe dans un câble à fibre optique sur la base dudit signal.
