Abstract
Le procédé selon l'invention consiste à utiliser un premier outil de diagraphie contenu dans une boîte 12 contenant une source pulsée de neutrons 13 commandée par impulsions par un circuit de commande 18a et un détecteur de neutrons résultant de l'irradiation de la formation environnante 10 pour envoyer à travers un câble 17 des signaux à un système de mesure comportant des compteurs 41 et 42 et un détecteur de rapport 45, et un second outil semblable au premier mais ayant une source continue de neutrons pour l'étalonnage d'après les résultats obtenus dans un trou foré dans une formation ayant une teneur connue en uranium afin d'obtenir par comparaison une indication représentant la concentration du minerai d'uraniumThe method according to the invention consists in using a first logging tool contained in a box 12 containing a pulsed source of neutrons 13 controlled by pulses by a control circuit 18a and a neutron detector resulting from the irradiation of the surrounding formation 10. for sending signals through a cable 17 to a measuring system comprising counters 41 and 42 and a ratio detector 45, and a second tool similar to the first but having a continuous source of neutrons for calibration according to the results obtained in a hole drilled in a formation having a known uranium content in order to obtain by comparison an indication representing the concentration of the uranium ore
