【摘要】 准噶尔盆地东北缘石炭系烃源岩在准东和腹部地区分布广泛,结合露头资料、钻井资料和地震资料,对准噶尔东北缘地区石炭系烃源岩的丰度、类型、成熟度特征进行了系统研究和评价,研究区烃源岩以凝灰岩和沉凝灰岩为主,是一套有机质丰度较高的混合偏腐殖型的成熟烃源岩,具有较高的成烃潜力。其油气主要分布在五彩湾凹陷、三个泉凸起上,该区的烃源岩有机质丰度以中等—好为主,有机质类型以Ⅱ型为主,有机质基本上处于成熟演化阶段,充分证实石炭系在准噶尔东北缘是一套有效的烃源岩,在该区寻找石炭系原油具有现实意义。

【Abstract】 The distribution of hydrocarbon source rocks of northeast margin of carboniferous in Junggar basin are wide in East Junggar basin and abdominal area.Combining outcrop material,drilling date and seismic data,the abundance,type and maturity characteristics systematically of carboniferous hydrocarbon source rock in the northeastern margin of Junggar basin will be researched and evaluated.Tuff and sedimentary tuff are the main type of the studying area.It is a set of mature hydrocarbon source rocks which has a great organic matter abundance,which is mixed the type and composite.It has great potential of oil source.Its oil and gas are mainly distributed in the Wucaiwan depression and three spring bumps.Organic matter abundance of the hydrocarbon source rocks is given priority to medium-good type,and organic type is mainlyⅡ type.Organic matter is basically in the mature evolution stage.Fully confirmed that the northeast margin of Junggar basin of carboniferous has a set of effective hydrocarbon source rocks,and there has the realistic value of researching the carboniferous crude oil.
