| 摘 要： | 延长东部地区山西组烃源岩可分为两种类型,其一为主要发育在上部山1段的泥岩型烃源岩,另一种类型为煤系烃源岩,发育在下部山2段。经判定,山西组暗色泥岩属于好烃源岩范畴,烃源岩有机类型为腐泥腐殖型(Ⅱ2型)和腐殖型(Ⅲ型),泥岩型烃源岩处于高-过成熟生气阶段,研究区可作为天然气的有利勘探区。

| Abstract: | There are two types in hydrocarbon source rock of shanxi formation,the one is mudstone type hydrocarbon source rock which was distributed in the upper Shan 1 member,the other is coal hydrocarbon source rock,which was distributed in the bottom Shan 2 member.After a judge,the dark mudstone of shanxi formation in this research area belongs to the category of good hydrocarbon source rocks,the organic matter type of the hydrocarbon source rocks consists of hybrid sapropel-humic organic matter(Ⅱ2 type)and humic organic matter(Ⅲtype).The mudstone type hydrocarbon source rocks in high maturity stage of evolution and can be explored for natural gas. |
