摘要

苏鲁一带不同还原型镜质组的显微岩石学特征和生烃潜力对比研究表明

较强还原型镜质组显着不同于较弱还原型镜质组

前者含有丰富的荧光镜质体

具有较低的反射率、较强的相对荧光强度、较短的最大荧光强度波长、较高的氯仿抽提物产率和生油潜量

尤其表现在R

0.6%～0.9%煤阶范围内。说明较强还原型镜质组相对富氢

具有较高的生烃潜力

特别是生成液态烃的潜力。较强还原型镜质组是较强还原型腐殖煤生油的重要母质。

Abstract

The micropetrological characteristics and hydrocarbon-generating potential of different reduction type vitrinite collected in Jiangsu-Shandong were studied.The results show that the vitrinite of strong reduction type is much different from that of weak reduction type.The former has rich fluorescent vitrintite

lower reflectance

stronger relative fluorescence intensity

less spectral maximum

higher yields of chloroform bitumen and oil potential

especially R

ranges from 0.6% to 0.9%.All of them suggest that the vitrinite of strong reduction type is relatively rich in hydrogen

and has higher hydrocarbon generation potential

particularly for liguid hydrocarbon potential.Therefore

this type of vitrinite is an important parent substance of oil generauon for strong reduction type humic coal.
