| 摘 要： | 白家海凸起是一个受南、北两排雁行式断裂带所夹持的继承性古隆起,紧邻生烃凹陷,是整个盆地油气富集程度较高的地区之一.这两排断裂断开的层位较深,直至下伏二叠系烃源层,且断裂的活动时期与源岩大规模生排烃时期相匹配,起油气运移通道的作用.由于雁行式断裂带位于白家海凸起侧翼,对凸起主体构造圈闭形态没有大的破坏作用,已聚集的油气藏得以保存.综合分析认为断裂是白家海地区油气成藏的主控因素.

| Abstract: | Baijiahai convexity is a inherited paleo-uplift controlled by two en-echelon fault zones north and south.It closes to hydrocarbon source sags,and is one of oil & gas enrichment areas in Junggar Basin.The two en-echelon fault zones incise so deep down to Permian formation.The fault zones are very important hydrocarbon migration pathways because the period of faulting is matching to the time of hydrocarbon generation.As the en-echelon faults in flanking Baijiahai uplift,the main structural traps on the convex shape are of major damages,and the role of reservoirs have been preserved together.Comprehensive analysis shows that fault is Baijiahai region controlling factors for hydrocarbon accumulation. |
