摘要： 准南前陆冲断带中段是 目前准噶尔盆地勘探的重点目标区,通过对准南前陆盆地石油地质综合研究,明确了该地区油气具有“近源”“近断裂”分布及晚期成藏等特点,指出该地区油气成藏的主控因素为烃源断裂和储集层,并总结出了“源上一背斜一断裂和相控”及“近源一断背斜一断控”两种油气成藏模式。通过对中段三排构造对比及综合研究,指出了第二、第三排构造带中部成藏组合为今后勘探的有利目标,对指导南缘的油气勘探具有重要指导意义。

Abstract: The mid-segment of foreland thrust belt in southern Junggar basin is the key area of interest for exploration of the whole basin. Comprehensive study shows that oil and gas in this area is characterized by proximal and near-faulting distribution as well as late accumulation. The main factors for controlling the petroleum accumulation are source-communicated faults and reservoir rocks. It is suggested that there exist two models of petroleum accumulation such as above source rocks-anticline-faulting-facies control and proximal distribu-tion-faulted anticline-faulting control. The related comparison indicates that in the second and third rows of anticline structural zones, thefavorable area of interest for further petroleum exploration would be the middle reservoir combination, which is of significance to guide the petroleum prospecting efforts in southem margin of Junggar basin.
