摘　　要：在铀矿勘查工作中，揭露到的富铀矿体铀含量可达5％-10％，甚至更高。γ测井规范中指定的FD-3019型γ测井仪检定线性上限为2％（核工业国营263厂，1989），遇铀含量超出测量上限时，会出现溢出现象。为满足热液型铀矿床高含量测井的需要，在FD-3019改进型γ测井仪基础上，研制了FD-3019增强型γ测井仪，通过了实验室测试和野外测井实际应用．对当量铀含量为2％～6％时，应用效果良好，基本满足富铀矿体测井需要。Abundant uranium ore can be discovered in the uranium exploration. Sometimes the uranium concentration can be more than 5% - 10% , even higher. The measure maximum of FD-3019 γ-Ray logging Instrument is 2% in the specification foil/logging,if the uranium concentration is more than 2%, will appear over measure maximum. To meet the hydrothermal type uranium deposit high levels uranium exploration, FD-3019 γ-Ray logging Instrument （Enhanced Type） is developed on the basis of γ-Ray logging Instrument （Improved Type）. The resules of γ-Ray logging on the uranium concentration between 2% - 6% have been verified by the test in the laboratory and logging in fieldwork, which can meet the requirements in the abundant uranium oreγ -Ray logging.
