Abstract

L'invention concerne un appareil (10) de fond formé d'un corps tubulaire principal (12) et d'au moins un canal (14) d'écoulement situé sur le corps. Le canal (14) présente au moins une dimension non uniforme. Un guide (16) d'écoulement est situé de manière adjacente à une extrémité du canal (14), et le guide (16) d'écoulement et le canal (14) définissent ensemble une trajectoire d'écoulement d'un milieu de fond le long du corps. L'appareil de fond peut être, par exemple, un sabot d'aléseur, un tuyau de forage, ou un manchon de moteur.
