Abstract

- L'invention concerne un procédé pour construire une image d'une zone du sous-sol, représentative de la résistivité et de la chargeabilité de la zone, à partir de systèmes d'acquisition indépendants les uns des autres, que l'on positionne de façon distribuée. On enregistre simultanément des mesures d'intensité du courant et des mesures de différences de potentiel entre deux dipôles orthogonaux. Ces données sont stockées dans les systèmes d'acquisition en y associant un temps d'enregistrement et une position géographique, avant d'être organisées selon le temps d'enregistrement, puis filtrées et accumulées. Enfin, on construit l'image en déterminant des données apparentes de résistivité et de chargeabilité, à partir de ces mesures accumulées et filtrées.The invention relates to a method for constructing an image of a subsoil zone, representative of the resistivity and chargeability of the zone, from acquisition systems independent of each other, which are positioned in a distributed fashion. Current intensity measurements and potential difference measurements between two orthogonal dipoles are simultaneously recorded. These data are stored in the acquisition systems by associating a recording time and a geographical position, before being organized according to the recording time, then filtered and accumulated. Finally, the image is constructed by determining apparent resistivity and chargeability data, from these accumulated and filtered measurements.
