| 摘 要： | 对在模型中进行地层元素中子伽马能谱测井实验和中子伽马谱解析方法进行了研究，即对非弹伽马谱与俘获伽马谱解析方法进行了研究。理论上推导出分别用非弹谱和俘获谱求出地层元素质量分数的公式。采用两谱联合分析及归一的方法，求出岩石骨架和孔隙流体整个地层中元素的质量分数。并在油田进行了实际应用，应用结果显示该方法是成功的

| Abstract: | The logging experiments and the analytical methods with neutron-Gamma-ray spectra from simulative formation elements are studied in the model boreholes. Namely, the analytical methods are studied for inelastic & capturing Gamma-ray spectra, respectively. The formulae of the quality fractions of the formation elements are derived theoretically by means of the inelastic & capturing Gamma-ray spectra, respectively. Two spectra union analytical and normalizing methods are used. The quality fractions of all formation elements in rock matrixes and porous fluid are found out. The practical applications are performed in oil field. The results show that the method is successful. |
