| 摘 要： | 乌尔逊凹陷断裂的形成具有较明显的分期特征,通过分析构建层序界面、生长指数、断层活动速率以及伸展率等,得出本区断裂的形成演化先后经历了早期伸展、中期走滑和晚期反转三个阶段;结合各变形时期的主要断裂对油气成藏的影响,认为伸展断陷期的主要控陷断裂控制了烃源岩的分布;主要控陷断层是油气运移的主要通道;伊敏组沉积末期形成的南北向断裂与长期发育的北东东向油源断裂近正交组合,在大磨拐河组和伊敏组形成大量的圈闭,是油富集的主要区带.

| Abstract: | The formation of faults in Wuerxun depression has obvious characters of substage,by analysising the tectonic sequence boundaries,growth index,faults acting rate and stretch,we considered the evolution of the fault had under gone early extension,middle strile-slip and late reversion three stages.By researching the effection of the main faults formed in different periods on hydrocarbon,we have concluded the main faults which controled the depression controled the distribution of hydrocarbon rock;the main cont... |
