Title (EN) FORMATION TESTER TOOL ASSEMBLY
(FR) ENSEMBLE OUTIL TESTEUR DE FORMATION
Abstract:
(EN) A formation tester tool (10) can include a longitudinal probe drill collar (12) having a surface, a formation probe assembly (50) located within the probe drill collar, the formation probe assembly including a piston (96) reciprocal between a retracted position and an extended position beyond the probe drill collar surface, the piston being slidingly retained within a chamber (94) , a seal pad (180) located at an end of the piston, the seal pad including an outer surface defining a partial cylindrical surface. The piston includes an outer surface having non-circular cross-sectional shape and the chamber includes an inner surface having a non-circular shape similar to the shape of the piston outer surface. The formation tester tool can include interchangeable draw down assemblies and a flow bore having a curving path.
(FR) Outil testeur de formation (10) pouvant inclure une masse-tige de sonde longitudinale (12) dotée d’une surface, et un ensemble sonde de formation (50) situé au sein de la masse-tige de sonde. L'ensemble sonde de formation comporte un piston (96) pouvant alterner entre une position rétractée et une position étendue, au-delà de la surface de la masse-tige de sonde, le piston se rétractant en coulissant dans un compartiment (94). Un patin d’étanchéité (180) est situé à l’extrémité du piston et comprend une surface extérieure définissant une surface cylindrique partielle. Le piston possède une surface extérieure dont la forme en section transversale n’est pas circulaire et le compartiment possède une surface intérieure de forme non circulaire similaire à la forme de la surface extérieure du piston. L’outil testeur de formation peut comprendre des ensembles de rabattement interchangeables et un alésage d’écoulement en courbe.
