Abstract
A production logging tool to analyze at least one property of a multiphase fluid mixture flowing in a hydrocarbon well has an elongated cylindrical housing shape and comprises a central pressure-resistant rigid housing carrying a centralizer arrangement. The production logging tool further comprises a deploying arrangement nested within the centralizer arrangement comprising deploying arms circumferentially positioned between two centralizer arms, and downhole fluid properties analysis probes secured on each deploying arm such as to expose a tip of said, at least one, probe to the multiphase fluid mixture flowing in the hydrocarbon well. The deploying arrangement follows radial movements imposed by the centralizer arrangement to radially and/or angularly position the tip of the probes in a first circumferential zone of a hydrocarbon well section substantially perpendicular to a longitudinal axis of the well.
