利用常规测井资料确定黏土矿物含量的方法研究

Method of determining clay mineral content by using conventional logging data

针对缺少自然伽马能谱测井资料的地区,以X衍射黏土矿物分析数据为基础,利用常规测井资料,应用多元非线性回归方法,借助灰色理论综合预测技术来确定黏土矿物含量。实际资料处理结果表明,该方法可准确确定黏土矿物含量,可为储层评价及储层敏感性分析提供可靠的理论依据。

Based of X-ray analysis, conventional logging data combined with muhielement nonlinear regression and grey theory analysis are applied to determine the clay mineral content in the area where is poor in natural gamma ray spectrometry log. The result shows that the method is accurate for determining the clay mineral content, so it can provide theory foundation for reservoir evaluation and sensitivity analysis.
