A system for communicating between a first location and a second location comprises a jointed tubular string (4) having a first section (21) and a second section (22) connected at a connection joint (4), with the tubular string having a fluid (11) in an internal passage thereof. A first acoustic transducer (23) is mounted in the internal passage of the first section (21) proximate the connection joint (4), and a second acoustic transducer (25) is mounted in the internal passage of the second section (22) proximate the connection joint (4). A signal transmitted from the first location to the second location is transmitted across the connection joint as an acoustic signal in the fluid (11) from the first acoustic transducer (23) to the second acoustic transducer (25).
L'invention concerne un système de communications entre un premier emplacement et un second emplacement, qui comprend une chaîne tubulaire (4) à première (21) et seconde (22) parties reliées par un raccord (4), avec fluide (11) dans un passage interne. On monte un premier transducteur acoustique (23) dans le passage interne de la première partie (21) près du raccord (4), et un second transducteur acoustique (25) dans le passage interne de la seconde partie (22) près du raccord (4). Un signal transmis depuis le premier emplacement vers le second emplacement traverse le raccord comme signal acoustique transmis dans le fluide (11) d'un transducteur (23) à l'autre (25).
