| 摘 要： | 准噶尔盆地腹部现今处于前陆盆地坳陷中。侏罗纪车莫古隆起的发育,一方面为早期成藏提供了构造背景,另一方面古隆起控制了河流三角洲砂体发育,不整合、地层超覆的分布。故本区形成了地层、岩性、断层三者复合的隐蔽油气藏发育区。后期剧烈的掀斜,导致古隆起周围圈闭类型、圈闭有效性发生变化或减弱。油藏多经历了后期调整、晚期充注,且类型多样。腹部地质背景及其演化,决定了油气形成与分布主要与古隆起及演化有关。

| Abstract: | The deep sag was located in the depression of the Junggar foreland basin.The early hydrocarbon accumulation in reservoirs,the development of fluvial-delta sand body and the distribution of unconformity and sequence overlaps were controlled by the Chepaizi-Mosuowan paleo-uplift formed in the Jurassic.The subtle reservoirs consisted of stratigraphic,lithologic,faults or their combination were developed in the area.Due to late strong tilting,trap types and their validity around the paleo-uplift were changed.Th... |
