N451γspectrometry logging probe is developed to accurately measure the content of uranium and thorium of the layer in uranium deposit mixed with thorium,and the probe is connected to HD 4002B light integrated logging system to constructγspectrometry logging system.Based on this system,γspectrometry logging techniques are studied,and correction method of the probe,data processing method ofγspectrometry logging and working method of field logging are established.The probe is of high detection efficiency and its auto spectrum stabilization system is strong in preventing radiation.Therefore,it can be used to continuously and effectively measure the content of uranium and thorium of the layer around the borehole inγspectrometry logging for uranium exploration.
