利用自然伽马能谱测井定量计算粘土矿物成分方法初探

Preliminary Investigation on Quantitative Analysis of the Composition of Clay Minerals Using NGS Log.

石强．利用自然伽马能谱测井定量计算粘土矿物成分方法初探．测井技术，１９９８，２２（５）：３４９～３５２根据自然伽马能谱测井应用现状，综合分析自然伽马能谱测井中粘土矿物特征值，对原定性解释图版进行解剖。在理论计算与实际资料标定相结合的基础上，总结出各种粘土矿物成分与自然伽马能谱测井之间的关系，进行了粘土矿物成分定量计算的初步探讨。

According to the current application status of NGS log, the qualitative analysis chart is improved after analysing the characteristic values from NGS log. Combining the theoretical computation with the analysis of actual data, the relation between the composition variation of clay minerals and NGS log is summarized. A new quantitative analysis chart is given to calculate the clay mineralogical composition.
