摘　　要：为了研究鄂尔多斯盆地吴定地区烃源岩油源对比,通过萜烷、甾烷生物标志化合物特征,厘定油源关系。原油和源岩的分析表明,长8储集层原油与长7烃源岩有密切的亲缘关系,而与长9烃源岩可比性差。因此,长8的原油来源于长7烃源岩。To discuss oil-source correlation of source rocks in Wuding area,Ordos basin,by means of biomarker features of terpanes,steranes,It reveals oil-source correlation.Analysis of crude oil and source rocks indicate that crude oil from chang8 reservoir has a relatively close relationship with chang7 source rocks and there is a poor correlation between crude oil from chang8 reservoir and chang9 source rocks.Therefore,chang8 crude oil is from chang7 source rocks.

关 键 词：原油 烃源岩 生物标志化合物 油源对比 吴定地区 鄂尔多斯盆地
