中文摘要：

记载的多元素 gamma 光线光谱为它的解释要求单个元素的标准系列。自从标准元素，系列通常用一个纯元素或它的氧化物的蒙特卡罗模拟被导出，我们综合了标准中子捕获了系列(作为将用一个 NaI ( Tl )察觉者被观察)元素 H ， Si ，从每个元素和它的氧化物的 Ca 和 Fe 。从元素和氧化物比较标准系列，我们与十个不同的孔各操作了沙岩，石灰石和石灰石的三模拟，并且使用了二种标准系列分析从沙岩和石灰石形成建模的混合系列。结果证明从氧化物的标准元素系列从纯元素比标准系列有更突出的精力山峰。当从氧化物的标准元素系列被用来分析形成时，计算形成元素内容接近理论价值混合系列。因此，形成元素标准系列应该在中子的分析从氧化物模型被计算由记载工具的捕获的系列。

英文摘要：

Multi-element gamma-ray spectrum logging requires standard spectra of individual elements for its interpretation.Since the standard element spectra are usually derived using Monte Carlo simulation of either a pure element or its oxide,we synthesized the standard neutron captured γ spectra（as would be observed using a NaI（Tl） detector） of elements H,Si,Ca and Fe from each element and its oxide.To compare the standard spectra from the elements and oxides,we operated three simulations of sandstone,limestone and mixed formation of sandstone and limestone each with ten different porosities,and used the two kinds of standard spectra to analyze the mixed spectra modeled from sandstone and limestone formations.The results show that the standard element spectra from oxides have more prominent energy peaks than the standard spectra from pure elements.The calculated formation element contents are close to the theoretical values when the standard element spectra from oxides are used to analyze the formation mixed spectra.Therefore,the formation element standard spectra should be calculated from oxide models in the analysis of neutron captured γ spectra by logging tools.
