摘要

自然γ测井铀定量属"间接铀定量"技术

须利用铀镭平衡、射气逸出等参数修正来校准铀含量。分析了天然放射性核素与特征γ射线的关系

提出了基于高精度γ能谱测井和234mPa特征γ射线（1.001 MeV）光电峰或能量窗的"直接铀定量"方法

利用自主研发的基于LaBr3（Ce）的γ能谱测井仪进行模型井实验

初步验证了方法的可行性。

Abstract

Uranium detection from natural γ-ray logging is an indirect method

because the uranium content must be corrected for influence factors from uranium-radium balance and radon escaping.In this article

relationship of the natural radio-nuclides and their characteristic gamma-rays is analyzed.A direct uranium quantitative detection method is proposed

based on high-precision γ-logging and the photoelectric-peak(or energy-window) from234mPa γ-ray of 1.001 MeV.In standard-model well experiments using a γ-spectrum logging instrument developed in our laboratory

and a LaBr3(Ce) detector

feasibility of this new method is verified.
