| 摘 要： | 本文分析了目前常用的γ能谱测井平均含量法、传统剥谱法对不饱和混合矿层（铀、钍、钾元素的含量在矿层中分布不均匀）的定量解释存在的原理缺陷；提出了利用γ能谱测井分离铀、钍、钾元素的定量解释新方法—逐点剥谱的单元层定量解释法，简单讨论了该解释方法涉及的形态系数、换算系数和单元层饱和度的确定，以及反形态系数的计算问题.

| Abstract: | The paper analyzes the quantitative interpretation method on unsaturated ledge(the content of uranium,thorium and potassium distribute unevenly in ledge) of traditional spectrum striping method and average content method.Their limitation is presented.The unit layer quantitative interpretation method adopting point-by-point spectrum striping is introduced.It is a new quantitative interpretation method separating uranium,thorium and potassium using gamma-ray spectrometric logs.The essential technologies such as shape coefficient,converted parameter,confirming saturation of unit layer and calculation of inversion shape coefficient related to the new method are discussed briefly. |

| Keywords: | traditional spectrum striping point-by-point spectrum striping unit layer quantitative interpretation Inversion shape coefficient gamma-ray spectrometric log |
