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.
