摘要： 吉6井位于准噶尔盆地东部吉木萨尔凹陷东坡,井下岩心显示出上二叠统芦草沟组、下仓房沟群发育。本文研究了吉6井井段1650～2010m岩样孢粉组合特征和井段1821.06～1920m原油样品孢粉集合类型,建立了井下上二叠统孢粉组合的层序,指出原油孢粉集合为单一型,属自生自储,吉6井油源岩为上二叠统芦草沟组。

Abstract: Well J一 6 is located on the eastern slope of the Jimsar Sag which is on the eastern margin of the Junggar Basin. The core in the well shows that is developed Lucaogou Formation in the Upper Jijicao Group and the Lower Cangfangou Group. In the present paper the sporo-pollen assemblage feature from the samples of depths of 1650 to 2010m and the type of me sporo-pollen assemblage from the crude oil sample of depths of 1821.06 to 1920m are studied. The sequeces of the sporo-pollen assemblage in the Upper Permian in the well are seted. It can be referred to a monotonous type of petroleum sporo-pollen assemblage. The oil source rock is coincident with the reservoir rock in age. The oil source rock in the well J—6 is considered being the Lucaogou formation.
