A heated fluid injection string (106) injects heated treatment fluid into a well (102) in a subterranean zone (112) and generates an acoustic signal. An acoustic detector (212) detects the acoustic signal, and an acoustic signal analyzer (214) interprets the detected acoustic signal. In some implementations, the acoustic signal analyzer (214) interprets the detected acoustic signal to determine information about at least one of the heated fluid injection string (106), the well (102), or the subterranean zone (112).

L'invention concerne une chaîne d'injection de fluide chauffé (106) qui injecte du fluide de traitement chauffé dans un puits (102) d'une zone souterraine (112) et génère un signal acoustique. Un détecteur acoustique (212) détecte le signal acoustique, et un analyseur de signal acoustique (214) interprète le signal acoustique détecté. Dans certaines réalisations, l'analyseur de signal acoustique (214) interprète le signal acoustique détecté pour déterminer des informations relatives à la chaîne d'injection de fluide (106), et/ou au puits (102) et/ou à la zone souterraine (112).
