摘　　要：对传统的有机生油凹陷理论提出质疑,并对盆地内已出现的三大油气富集带进行地质解释,指出这是盆地内富含油气的特殊的深部地壳结构(上地幔上拱、中下或中上地壳内存在低速高导层、以近南北向为主的壳幔断裂发育)与其上沉积盖层相互依存、相互作用的结果。对今后盆地勘探提出了与传统有机生油凹陷理论完全不同的新思路、新举措。This article proposes the queries on traditional organic source sag theory and new geological interpretation on three major petroleum-enriched belts in Junggar basin, suggesting that these belts are resulted from inter-existence and interaction among the specific deep crust structures in this petroliferous basin such as upper mantle upwarp, low-velocity high conductivity strata in middle-lower or middle-upper crust, crust-mantle fault mainly developed near south-north direction and the sedimentary cap rocks over them. Meanwhile, this article proposes novel thought and measures completely different from the old or traditional organic source sag theory for further exploration in Junggar basin.
