Abstract

A downhole tool for investigating an outside fluid flow being adapted to operate in a well bore is presented. The downhole tool comprises a housing surrounded by an outside fluid and at least a first wave generator device. The first wave generator device preferably comprises a directional sound generator, for coupling waves into the surrounding outside fluid. The waves therein are scattered, for example, reflected, at inhomogeneities in the outside fluid, for example particles, scatterers and/or water in oil, thereby generating reflections. Said reflections are measured with a receiver device for receiving said reflections, and are evaluated using an evaluation device for determining first positions of said inhomogeneities in the outside fluid by evaluating said reflections, wherein the evaluation device is adapted to determine the outside fluid flow.
