摘要

利用有机岩石学全岩分析技术,依靠反射光、透射光和荧光相结合,系统研究了高邮凹陷泰州组烃源岩显微组分组成、分布特征及主要组分对生烃的贡献,希望为资源评价和今后油气勘探提供依据。泰州组烃源岩显微组分含量占全岩体积的9.92%;且在平面上存在显著的非均质性,东部含量较高,而西部较低。显微组分组成呈现出腐泥组和壳质组占优势,镜质组较少,惰性组贫乏的特点。矿物沥青基质、藻类体和壳屑体是泰州组烃源岩主要生烃组分,对油气生成贡献最大。

Abstract

We systematically studied the composition,distribution characteristics,and contribution to hydrocarbon generating of the hydrocarbon source rock macerals from the Taizhou Formation in Gaoyou depression using the bulk-rock analysis technology of organic petrology,which could provide a basis for resource evaluation and oil exploration.The macerals of hydrocarbon source rocks from the Taizhou Formation,with the content of 9.92% of the whole-rock volume,were distributed heterogeneous notably on the flat surface,the maceral content of the east Gaoyou depression higher than that of the west.The macerals were rich in exinite and sapropelite,while less in vitrinite,and poor in inertinite.The main components of hydrocarbon generation from Taizhou source rock were Alginite,mineral bituminous matrix and liptodetrinite.
