| 摘 要： | 乌尔逊断陷盖层构造演化主要经历了断陷和反转两个阶段断陷期的构造演化具明显的幕式特征，铜钵庙组一大磨拐河组时期主要发育了张性基底断块构造样式，伊敏组时期则以滑脱型构造样式的发育为特色；构造反转发生在伊敏组沉积末期，断陷西北部的正断层普遍反转，同时全区抬升并遭受剥蚀。研究认为，乌尔逊断陷含油气系统的烃源岩演化、油气的运聚、油藏类型及含油气系统的关键时刻等明显受构造演化的控制。

| Abstract: | The tectonic evolution of Wuerxun Depression mainly underwent two stages from depression to inversion. It is characterized by episode in the depression period, which extensional basement fault- block during Tongbomiao- Damoguaihe period and detachment structural styles in Yimin period were developed. Structural inversion occurred in later Yimin period is characterized by inversion of normal faults in the northwest of the Depression, and the area was uplifted and eroded. The paper points out that structural evolution is the main function in controlling the hydrocarbon generation,migration and accumulation of oil/gas, reservoir types, and critical moment of petroleum system of Wuerxun Depression. |
