同沉积构造对油气成藏的作用--以济阳坳陷为例

从构造、沉积、成藏相互关系分析的角度,系统论述了济阳坳陷同沉积构造对沉积和油气成藏的控制作用,揭示了同沉积构造有利于油气生成、运移、聚集、保存的基本条件.分析认为,在大中型油气藏相继被发现之后,当前济阳坳陷应该充分运用层序地层学理论、含油气系统理论及成藏动力学理论,研究同沉积构造的发育演化过程对沉积过程、圈闭形成过程以及成藏过程的控制作用和空匹配关系,以提高勘探效果.同沉积构造的研究日趋由定性向定时和定量方面发展,不但更加重视动力机制研究,也开始逐步完善定量化过程模拟.

Function of Syndepositional Structure on Oil-Gas Reservoir Forming:Jiyang Depression as an Example

Based on the analysis on the relationship between structure,sedimentary and reservoir forming,this paper has systematically discussed the control function of syndepositional structure on sedimentary and oil-gas reservoir forming in Jiyang depression,and exposes that syndepositional structure is a great advantage for oil-gas generation,migration,aggregation,and conservation.The paper also points out that after the large or middle sale oil-gas pools have been discovered one by one, in order to improve the exploration effect,the theory of Sequence Stratigraphy,petroliferous system,and reservoir forming dynamics should be used in Jiyang depression to research the control function of the development and evolution process of syndepositional structure on sedimentary,trap and reservoir forming and their relationship with time and quantity.Not only dynamic mechanism was paid regard to in the research,but the simulation of quantitation is going to be perfect step by step.
