摘要: 对准噶尔盆地石炭系下石炭统滴水泉组烃源岩质量分析表明,该套烃源岩有机质丰度较高,有机质类型为Ⅱ2—Ⅲ型,以Ⅲ型为主,烃源岩现处于成熟—高成熟阶段,是良好的气源岩,生气潜力较大。天然气地球化学特征对比表明,彩南及陆东—五彩湾石炭系天然气与盆地其它地区不同,其甲、乙烷具有较重的碳同位素值特征(δ13C1>-33‰,δ13C2>-28‰),表现出明显的偏腐殖—腐殖型母质来源,与石炭系烃源岩具有良好的对比关系。资源计算证实,石炭系油气资源丰富,勘探潜力很大,陆东—五彩湾、莫索湾及其北部是今后石炭系勘探的主要地区。Abstract: Based on the integrated study of Carboniferous Dishuiquan Formation source rock in the Junggar Basin,it is suggested that the organic matter abundance ratio is high,the kerogen type belongs to Ⅱ2-Ⅲ and it is at the mature or high mature stage.Therefore,it is good gas source rock and has large gas resource potential.The gas geochemistry features indicate that the Carboniferous gas in Cainan and Ludong-Wucaiwan is different from others in the Junggar Basin,and the methane and ethane carbon isotope of it are heavier(δ13C1-33‰,δ13C2-28‰),indicating that the gas sources from sapropelic kerogen and comes from Carboniferous sourse rock.In brief,the oil and gas resources of Carboniferous is plentiful,and the exploration foreground is very vast,and Ludong-Wucaiwan,Mosuowan are the main area of Carboniferous exploration in the future.
