Abstract

One hundred and eighty-three species of fossil spores and pollen were identified，that are referred to 89 genera found in 44 crude oil samples and 3 natural gas samples collected fromthe North Tarim，Kuche,Kashi and Yecheng petroliferous regions of Tarim Basin. Based on the investigations of the fossil spores and pollen found in oil and gas，the mechanisms of petroleum migration were discussed according to the geological background of the basin. The contents of this study include the passages,phase states,directions，routes and periodic sequences of petroleum migration. Judging from the spores and pollen in petroleum，it may be concluded that microfissures for med by abnormal high pressure during the diagenesis of petroleumsource rocks could provide passages for the primary migration of petroleum；faults,unconformity surf aces，joints and other fissures could be the passages of the secondary migration of petroleum；petroleum might keep in the original phase state in the course of migration,and liquid and gaseous mixed phase might be the main phase state in the course of petroleum migration in Tarim Basin ；and the main direction of petroleum migration could be represented by either vertical migration or lateral migration for different reservoir types.
