Title
(EN) HIGH QUALITY VISUALIZATION IN A CORROSION INSPECTION TOOL FOR MULTIPLE PIPES
(FR) VISUALISATION DE HAUTE QUALITÉ AVEC UN OUTIL D'INSPECTION DE CORROSION POUR TUYAUX MULTIPLES
Abstract
(EN)
A method includes conveying a pipe inspection tool including one or more sensors into a wellbore having at least one pipe, transmitting an excitation signal from the pipe inspection tool and measuring response signals with the sensors, and processing the response signals to obtain measured responses. A map of the pipe is then generated based on the measured responses, where the map is divided into pipe ranges extending along the length of the pipe and each pipe range corresponds to a percentage of metal loss in the pipe. A photorealistic image is assigned to each pipe range based on the percentage of metal loss, and a two-dimensional (2D) or three-dimensional (3D) image is then generated as a combination of each photorealistic image. The 2D or 3D image is then graphically visualized.

Selon l'invention, un procédé consiste à acheminer un outil d'inspection de tuyau comprenant un ou plusieurs capteurs dans un puits de forage constitué d'au moins un tuyau; à transmettre un signal d'excitation à partir de l'outil d'inspection de tuyau et à mesurer les signaux de réponse avec les capteurs; et à traiter les signaux de réponse pour obtenir des réponses mesurées. Une carte du tuyau est ensuite générée sur la base des réponses mesurées. La carte est divisée en segments de tuyau s'étendant le long du tuyau et chaque segment de tuyau correspond à un pourcentage de perte de métal dans le tuyau. Une image photoréaliste est attribuée à chaque segment de tuyau sur la base du pourcentage de perte de métal, et une image bidimensionnelle (2D) ou tridimensionnelle (3D) est ensuite générée en tant que combinaison de chaque image photoréaliste. L'image 2D ou 3D est ensuite visualisée graphiquement.
