摘要

该文通过对伊朗卡山地区侏罗系Shemshak组烃源岩有机质丰度、干酪根镜鉴结果、干酪根碳同位素特征、生物标志化合物特征等的分析,提出Shemshak组烃源岩干酪根类型主要为腐泥-腐殖型(Ⅱ2)和腐殖(Ⅲ)型.有机质演化大部分样品已达到过成熟阶段.Shemshak组烃源岩除了极少部分属好烃源岩以外,大部分为中等烃源岩.

Abstract

By analyses on the organic matter abundance of hydrocarbon source rocks,the vitrinite composition and carbon isotopic features of kerogen and the features of biomarkers in the Jurassic Shemshak Formation of Kashan area,Iran,it was suggested that the kerogen types of the Shemshak source rocks be mainly sapropel-humic(Ⅱ2) and humic(Ⅲ).Most samples have evolved to overmature stages.Except for a few good source rocks,most source rocks of the Shemshak Formation are middle grade.
