摘要

本文主要对四川盆地上三叠统煤系的红外光谱特征进行研究。据20余口井的资料分析,大致可分出与烷链结构有关、与苯环结构有关以及与含杂原子基团有关三类吸收峰,以反映上三叠统源岩、煤及原油组成特征,为判别源岩的沉积环境、有机质类型及生烃能力提供了依据。

Abstract

The characteristics of Infra -Red spectra for the upper Triassic coal series in the Sichuan Basin are studied.Based on the analysis on the data from more than 20 wells,three absorption peaks associated respectively with structures of alkane-chain,benzene ring and radicals of hetero-atoms have been distinguished,and it reveals the characteristics of the upper Triassic source rocks,coal and crude oil constitutions.In addition,the study provides basis for the determinations of sedimentary environment,organic types and oil gen-erating potential.
