摘要
采用有机岩石学全岩分析方法，剖析了苏北盆地下第三系低熟烃源岩。该盆地烃源岩具有藻类微生物与高等植物混合的生源构成，富含腐泥组，相对发育镜质组和壳质组。“腐泥组＋壳质组”含量与氯仿沥青、总烃和产油潜量呈密切正相关。确认藻类体和孢子体为其最主要的生烃组分，在此基础上建立了苏北盆地下第三系烃源岩的生烃模式。
By using the whole rock analytical method of organic petrology, a detailed study on the Paleogene low mature source rocks in Subei basin is made There are combined genetic source compositions of both algae microbe and high plants in the samples and rich sapropelinite, common vitrinite and exinite The content of “sapropelinite plus exinite” shows a close relation with the amount of chloroform bitumen, total hydrocarbon and oil potential Alginite and sporinite is suggested to be main macerals of hydrocarbon generation Based on the study, a hydrocarbon generation model of source rocks in Subei basin is established
