Abstract

Procédé permettant la détermination de la résistivité et de la constante diélectrique des terrains au voisinage d'un trou de sondage. Un bobinage émetteur émet des ondes électromagnétiques à environ 30 MHz. Deux bobinages récepteurs sont prévus à différents distances longitudinales de l'émetteur. On mesure le rapport d'amplitudes non normalisé et le déphasage relatif des ondes électromagnétiques détecté aux bobinages récepteurs es pacés. A partir d'une relation on obtient la constante diélec trique et la résistivité à partir des mesures de rapport d'ampli tudes et de déphasage relatif. Application dans l'exploration des terrains et notamment dans la recherche de terrains pétrolifères
