Abstract
L'invention concerne un appareil pour obtenir des paramètres de résistivité de formations de terre (7). Cet appareil utilise un couplage capacitif (5) pour injecter des courants de mesure dans une formation dans une boue non conductrice. Selon un mode de réalisation, on utilise un courant électrique modulé. Par ailleurs, des mesures multifréquences peuvent être prises pour obtenir le paramètre de résistivité. Selon un mode de réalisation facultatif, la fréquence de modulation se trouve dans la plage audio-fréquences, ce qui permet d'utiliser un circuit de l'art antérieur conçu pour réduire la diaphonie. Il est possible d'effectuer des mesures sur un câble métallique ou dans une configuration de mesure de fond pendant le forage.
