Abstract There are many hydrocarbon generation sags around Dishuiquan Oilfield, such as Dishuiquan Sag, Dongdaohaizi Sag, Wucaiwan Sag, etc. But there is no result which hydrocarbon generation sag the Jurassic oil of Dishuiquan Oilfield is sourced from. Through comparisons on carbon isotopes, sterane distributions and maturities of source rocks and crude oil, the result shows that the geochemical characteristics of Jurassic crude oil in Dishuiquan Oilfield are highly consistent with those of Permian source rocks in Dongdaohaizi Sag and have obvious differences with other sags, which indicates the crude oil comes from the Permian source rocks in Dongdaohaizi Sag.

准噶尔盆地滴水泉油田侏罗系油源对比

摘要 滴水泉油田周边存在多处生烃凹陷，如滴水泉凹陷、东道海子凹陷、五彩湾凹陷等，但滴水泉油田侏罗系油源生烃凹陷尚无结果。通过烃源岩和原油碳同位素、甾烷分布及成熟度对比，结果表明滴水泉油田侏罗系原油地球化学特征与东道海子凹陷二叠系烃源岩地球化学特征高度一致，与其他凹陷有明显差异,说明原油来自东道海子凹陷二叠系烃源岩。
