摘要：

近年来我国原油孢粉研究迅速地开展起来,大量的原油孢粉研究表明,原油中含有相当多的菌、藻、孢粉化石。孢粉由于体积小,比重轻,孢粉壁不易氧化,而且石油具有一定的粘度,故油气在其运移过程中,往往将生油岩中的孢粉带进油藏,所以原油中的孢粉化石可以示踪油气运移,查明油源,判断生油岩时代,是石油地质研究的有效手段之一。沙二段是胜利油田第三系的主要含油层系之一,对其油源和油气运移研究,不仅有理论价值,而且对于油气勘探也有一定的指导意义。

Abstract:

The fossil sporo-pollen assemblages found in the crude oil of the Second Member of Shahejie Formation in Shengli Oil Field have the same characte-ristics as those in the underlying Third Member,which indicates that theycame,in company with the migrating oil and gas,from oil source rocks ofthe Third Member.It follows that the study of characteristics of fossil sporo-pollens may behelpful to tracing the migration history of oil and gas,and is useful to theoil-to-source rock correlation.
