Abstract
L'invention concerne les sondes introduites dans un trou de forage et qui comportent une paroi latérale dilatée par un fluide incompressible. Pour faciliter le déplacement de la sonde, on soumet la paroi dilatable 8, 9, 10 à une contrepression de gaz apte à refouler le fluide incompressible et on purge ledit gaz après avoir obtenu ledit refoulement, en recueillant le volant de liquide résiduel dans des cavités adéquates. L'invention s'applique aux sondes pressiométriques.
