【摘要】 鉴定了从新疆塔里木盆地塔北隆起含油区原油中萃取出的孢子花粉化石66属135种，基于原油孢粉集合组成特征的研究，确定了该含油区油源岩的时代和层位，并讨论了油气运移的通道、方向、路线。期次等问题。研究结果确认，中三叠统克拉玛依组，上三叠统黄山街组和塔里奇克组；下侏罗统阿合组和阳霞组；中侏罗统克孜勒努尔组和恰克马克组是塔北含油区的重要油源岩系。更多还原

【Abstract】 One hundred and thirty-five species of fossil spores and pollen referred to 66 genera which were extracted from the crude oil samples collected from the North Tarim petroliferous region of the Tarim Basin wereidentified. Based on the investigations of the characteristics of the Petroleum sporo-pollen assemblages, the geological ages and formations of the petroleum source rocks of the petroliferous region were determined. Someaspects concerning the avenues, directions, routes, Periodic sequences of oil and gas migration were also discussed. The resultS of this study confirm that the following Formations, viz. the Middle Triassic Karamay Formation, the UPper Triassic Huangshanjie and Taliqike Formations, the tower Jurassic Ahe and YangXia Formations, and the Middle Junssic Kezilenuer and Qiakemake Formations should be the important petroletunsource rock series of the North Tarim petroliferous region.更多还原
