Title (EN) DOWNHOLE CORROSION, EROSION, SCALE AND DEPOSIT MONITORING SYSTEM
(FR) SYSTÈME DE SURVEILLANCE DE CORROSION, D’ÉROSION, DE CALAMINE ET DE DÉPÔT DE FOND
Abstract:
(EN) A tool for monitoring conditions within a subterranean well includes a first body segment, the first body segment being an elongated member with an axial protrusion having a reduced outer diameter. A second body segment is sized for mating with the first body segment. A metal specimen circumscribes the axial protrusion of the first body segment so that an outer diameter surface of the metal specimen defines an outer diameter of the tool. A connection assembly releasably secures the first body segment to the second body segment.
(FR) La présente invention concerne un outil pour surveiller des conditions dans un puits souterrain qui comprend un premier segment de corps, le premier segment de corps étant un élément allongé avec une saillie axiale ayant un diamètre externe réduit. Un deuxième segment de corps est dimensionné pour s’accoupler avec le premier segment de corps. Un échantillon métallique entoure la saillie axiale du premier segment de corps de sorte qu’une surface diamètre externe de l’échantillon métallique définisse un diamètre externe de l’outil. Un ensemble de raccordement fixe de façon amovible le premier segment de corps au deuxième segment de corps.
