The content of vitrinite and ash are different in different types of coals. 镜质组有利于割理的形成，其含量越高，储集物性越好。
The coal petrologic automatic analysis is realized mainly by means of random reflectance of vitrinite. 煤岩自动分析主要采用镜质组随机反射率自动测试技术来实现。
Based on experimental data, the functional relationship between displacement pressure of mudstone and vitrinite reflectance is set up. 本文在大量实验数据的基础上，建立了泥岩排替压力与镜质体反射率之间的函数关系。
This paper describes the calculation of the erosion thicknesses of Dongying Formation in single wells based on the vitrinite reflectance and sonic time difference data. 综合利用镜质体反射率和声波时差测井资料对东濮凹陷单井的东营组地层剥蚀厚度进行了计算。
