ABSTRACT:
To acquire data such as the flow rate of various phases of a fluid flowing in a hydrocarbon well (12) in production, in particular in an inclined or horizontal portion of the well, both the local speed of the fluid and the proportions of the various phases are determined in each of at least two distinct regions of the well that are not in alignment with one another parallel to the axis of the well. The regions in which the measurements are taken are advantageously distributed in a vertical plane containing the axis of the well when the well is inclined or horizontal.
