ABSTRACT:
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.
