CA 2444952
The invention relates to a tool holder serving to receive measurement means (9, 10, 13) for characterizing a multi-phase fluid coming from a deposit (17) through which at least one well (16) passes, and flowing inside said tool holder. According to the invention, the tool holder is provided with an axial cavity (3) and with a first radial opening (4) which opens out in the inside wall of said tool holder and intercepts said axial cavity, said cavity and said opening serving to receive said measurement means. The invention also relates to a device for characterizing a multi-phase fluid coming from a deposit (17) through which at least one well (16) passes, said device comprising: a source unit (9) for emitting gamma rays through said multi-phase fluid; and a detector unit (10) having a scintillator crystal (10a) receiving said gamma rays after they have passed through the fluid. According to the invention, said device further comprises a tool holder (1) of the invention, and the detector unit (10) is positioned in the axial cavity (3) of said tool holder so that the scintillator crystal (10a) is situated in the first radial opening (4) in said tool holder.
La présente invention concerne un porte-outil destiné à recevoir des systèmes de mesure (9, 10, 13) servant à caractériser un fluide à phases multiples provenant d'un gisement (17) à travers lequel passe au moins un puits (16), et s'écoulant à l'intérieur dudit porte-outil. Selon l'invention, le porte-outil comprend une cavité axiale (3) et une première ouverture radiale (4) qui s'ouvre vers l'extérieur dans une paroi interne dudit porte-outil et intercepte ladite cavité axiale, ladite cavité axiale et ladite ouverture servant à recevoir lesdits systèmes de mesure. Cette invention concerne également un dispositif servant à caractériser un fluide à phases multiples provenant d'un gisement (17) à travers lequel passe au moins un puits (16), ledit dispositif comprenant: une unité d'émission (9) servant à émettre des rayonnements gamma à travers ledit fluide à phases multiples; et une unité de détection (10) présentant un cristal scintillateur (10a) recevant lesdits rayonnements gamma après leur passage à travers le fluide. Selon l'invention, ledit dispositif comprend également un porte-outil (1) de l'invention, et l'unité de détection (10) est disposée à l'intérieur de la cavité axiale (3) dudit porte-outil de sorte que le cristal scintillateur (10a) se trouve dans la première ouverture radiale (4) à l'intérieur dudit porte-outil.
