准噶尔盆地腹部已发现石油集中分布在超压顶面上下有限区域内.聚焦超压顶面附近油藏原油地球化学特征和分布规律,发现中下二叠统湖相暗色泥岩和侏罗煤系是主要源岩,来源于两套源岩层的原油具有明显不同的地化特征.各构造单元不同来源的原油分布特点不同,盆1井西凹陷超压顶面之上均有源自中下二叠统烃源岩的原油,而超压仓内主要有源自中二叠统烃源岩的原油; 昌吉凹陷西段超压顶面附近主要是源自中二叠统烃源岩的原油,含有部分混源油; 东道海子北凹陷和昌吉凹陷东段石油主要为超压仓内的煤成石油.系统研究分析了准噶尔盆地腹部超压顶面附近石油地化特征.

Oil discoveries in central Junggar Basin are mostly concentrated within a limited area around the top overpressured surface. This paper focuses on geochemical characteristics and distribution of crude oil near the top overpressured surface. The outcomes mainly include: ① the Middle and Lower Permian lacustrine dark mudstones and the Jurassic coal measures are the major source rocks, with obvious different geochemical indicators; ② oil distribution characteristics and tectonic units of both above formation sources are different. In Pen 1 Jingxi Sag, crude oil comes from Middle and Lower Permian source rocks in the upper top overpressured surface, and the crude oil comes from Middle Permian source rocks in the overpressured compartment. In western Changji Sag, the majority crude oil comes from Middle Permian source rocks, but still contains some source-mixed oil. In Dongdaohaizibai Sag and Eastern Changji Sag, coal-derived oil accounts for the majority of oil in the overpressured compartment, the oil on this sites experienced two phases of capturing hydrocarbon, and two main hydrocarbons charging in the late phase. In general, this paper delivers a systematic analysis and summary of the geochemical characteristics and distribution rule around the top overpressured surface in central Junggar Basin.
