摘要： 从生油岩成熟作用史的角度出发,分析了准噶尔盆地西北缘、东部、腹部、南缘和北部地区石炭系生油岩对盆地内油气成藏的意义。石炭系生油岩尽管曾大量生、排过烃,但由于石炭系生烃凹陷无法确定以及早期成藏的油气遭受破坏的时间长,不易保存,故对勘探十分不利,建议寻找在以石炭系为主要烃源的油气藏时,应加强石炭系烃源岩分布及其成藏史的研究。

Abstract: Based on maturation history of source rock, this paper analysed the significance of Carboniferous source rock with respect to formation of reservoir in the northwest margin, east part, hinterland, south margin and north part of Junggar basin. Although Carboniferous source rock has generated and expelled large amount of hydrocarbon, oil and gas exploration comes into a very unfavorable situation because Carboniferous source sag failed to be determined, and reservoir formed in early period was destroyed for a long time. Therefore, it is necessary to deeper strengthen the research of distribution of Carboniferous source rock and reservoir history when searching for oil/gas reservoir mainly sourced from Carboniferous.
