Abstract
La présente invention concerne les moyens où la capacitance varie en raison de la variation de température et/ou de la pression dans un transducteur piézoélectrique utilisé pour la télémétrie acoustique dans un forage; la capacitance est décalée de manière dynamique en modifiant un ou plusieurs des paramètres associés avec les circuits d'entraînement ou de contrôle dudit transducteur. L'invention vise à maintenir de manière stricte le transducteur en mode de résonnance, assurant de la sorte une consommation d'énergie optimale.
