Leica QWin_V3图像处理软件在烃源岩有机岩石学定量分析中的应用

Application of Leica QWin_V3 image analysis software in organic petrologic quantitative study

全岩光片有机岩石学分析中有机显微组分的定量统计是一项较繁琐的工作。Leica QWin_V3图像处理软件能对图片中相似光性特征的部分进行选取及定量计算,采用该软件进行烃源岩有机显微组分定量分析,能较好地对同一视域中灰度或颜色相近的有机显微组分进行选取及面积定量计算。通过对煤样中有机显微组分的面积定量统计显示,该软件的应用可较客观快速地进行有机显微组分定量分析,提高全岩有机岩石学分析效率。

The quantitative analysis of whole rock macerals is a complex job for organic petrology. The Leica QWin_V3 image analysis software can select the macerals with similar gray scale or color and make quantitative analysis in selected area, such as circumference, diameter and so on. Area quantitative statistics of whole rock macerals of coal samples have proved that this software succeeds in organic petrologic quantitative study.
