Apparatus for determining the density of underground formations surrounding a borehole, such as a wireline logging tool or a logging-while-drilling tool, includes a neutron source for irradiating the formations from within the borehole and at least one detector which detects neutrons and gamma rays in the borehole resulting from the irradiation of the formations with neutrons. Multiple detectors can also be used to separately detect neutrons and gamma rays. Detected neutron and gamma ray signals are each analyzed and combined to determine the density of an earth formation.

Dispositif permettant de déterminer la densité des formations souterraines traversées par un trou de forage, comme un outil de diagraphie par câble ou un outil de diagraphie en cours de forage. Il comprend une source de neutrons pour irradier les formations à partir de l'intérieur du trou de forage et au moins un détecteur qui décèle les neutrons et les rayons gamma dans le trou de forage, qui proviennent de l'irradiation des formations à l'aide de neutrons. Des détecteurs multiples peuvent aussi être utilisés pour découvrir de manière séparée les neutrons et les rayons gamma. Les neutrons détectés et les signaux des rayons gamma sont analysés et combinés afin de déterminer la densité d'une formation.
