Title

(FR) PROCÉDÉS ET SYSTÈMES POUR MAINTENIR LA TRANSPARENCE OPTIQUE LORS DE L'ACQUISITION D'IMAGES DE PARTICULES
Abstract
(EN)
Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed. Wellhead imaging systems can comprise: a flow pathway extending from a wellbore; an electromagnetic radiation-transparent window external to the wellbore establishing optical communication with the flow pathway; an image acquisition unit in optical communication with the flow pathway via the electromagnetic radiation-transparent window; and a movable barrier that is also electromagnetic radiation-transparent and is disposed between the electromagnetic radiation-transparent window and the flow pathway.

Selon l'invention, l'encrassement ou l'endommagement d'une fenêtre transparente aux rayonnements électromagnétiques peut empêcher d'obtenir des images satisfaisantes avec une unité d'acquisition d'image, telle qu'un appareil photo. Certains types d'environnements peuvent être particulièrement enclins à favoriser l'encrassement ou l'endommagement, et un nettoyage manuel ou une réparation d'une fenêtre transparente aux rayonnements électromagnétiques peuvent être difficiles dans certaines circonstances. Ces problèmes peuvent être particulièrement répandus lors de l'imagerie des déblais de forage et d'autres solides obtenus à partir d'un puits de forage en raison de l'environnement d'échantillonnage complexe dans lequel ces solides sont souvent éliminés. Des systèmes d'imagerie de têtes de puits peuvent comprendre : une voie d'écoulement s'étendant à partir d'un puits de forage ; une fenêtre transparente aux rayonnements électromagnétiques extérieure au puits de forage établissant une communication optique avec la voie d'écoulement ; une unité d'acquisition d'images en communication optique avec la voie d'écoulement par l'intermédiaire de la fenêtre transparente aux rayonnements électromagnétiques ; et une barrière mobile qui est également transparente aux rayonnements électromagnétiques et qui est disposée entre la fenêtre transparente aux rayonnements électromagnétiques et la voie d'écoulement.
