Abstract

L'invention concerne un procédé et un appareil de réglage du couplage entre la plaque de base d'un vibreur sismique et le sol. Cet appareil comporte un dispositif de commande faisant vibrer la plaque de base et dont l'action dépend d'un signal d'entrée. Des capteurs de pression, reliés à la plaque de base, produisent un signal correspondant à la pression instantanée du sol sur la plaque. Une boucle de réaction traite le signal de pression et agit sur le signal transmis au dispositif de commande afin que l'amplitude des vibrations de la plaque de base diminue lorsque la pression entre le sol et la plaque descend au-dessous d'une valeur prédéterminée. Domaine d'application : prospection sismique
