乌夏地区隐蔽油气藏成藏条件及其分布规律

Research on accumulation conditions and distribution law of subtle reservoirs in Wuxia area

  • 摘要: 分析了乌夏地区隐蔽油气藏类型、成藏条件,并提出了隐蔽油气藏分布规律。研究区紧邻生油凹陷,烃源岩条件优越,冲断活动响应的各种沉积砂体提供良好的储集体,盖层封堵能力良好,不整合与断裂发育,构成立体输导网络,从而形成了岩性油气藏、地层油气藏、裂缝性油气藏和复合油气藏等多种隐蔽油气藏。研究认为构造因素与沉积相带是油气藏形成的主要控制因素,不整合面与断裂附近为油气藏有利发育区。

     

    Abstract: By analyzing the types and accumulation conditions of the subtle reservoirs in Wuxia area,the research on distribu-tion law has been carried out. The subtle traps in Wuxia area have great conditions for hydrocarbon accumulation,such as adequate sources,good reservoirs for sedimentary sand of the thrust activitie,good seal quality,developed unconformi-ties and faults,compositing three-dimensional migration network. Therefore,lithologic reservoirs,stratigraphic res-ervoirs,fractured reservoirs and combination reservoirs have been developed. The research finds that the subtle reservoir distributions are controlled by structure and depositional sys-tem,the favorable developed area is near the unconformities and faults.
