摘要
为准确测定铀钍混合型矿床中矿层的铀、钍含量,研制了N451型伽玛能谱测井探管,并将该探管配接在HD-4002B轻型综合测井系统上组成了伽玛能谱测井系统。基于该系统,建立了伽玛能谱测井仪的校正方法、伽玛能谱测井的数据处理方法和野外测井工作方法。N451型伽玛能谱测井探管具有探测效率高、自动稳谱系统抗辐射能力强的特点,在铀矿勘查中连续测定钻孔中矿层的U、Th含量,效果良好。
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.
