东濮凹陷Es3^上地层充填样式及储集砂体发育规律

Upper Formation Filling Shape and Rules of Reservoir Sandbody Growth in Dongpu Depression

根据高分辨率层序学原理,结合东濮凹陷构造演化史及其对沉积体系和不同层次基准面变化的控制作用,探讨了该凹陷演化不同阶段基底断裂对沉积体系、沉积相、地层堆积样式的控制,进而讨论了基底断裂对中长期基准面变化的控制作用,认为在凹陷强烈断陷期基底断裂是控制基准面变化的主要控制因素,指出了基准面变化过程中储层的发育分布规律。

In combination with tectonic evolutional history and its control to the sedimentary system and changes of different base-levels in the depression, the control of basement fracture to the sedimentary system, sedimentary facies and the shape formation accumulation in Dongpu Depression at different stages are approached based on the theory of high resolu- tion stratinomy, then the control of basement fracture to the medium-long term base-level changes is discussed. It is considered that in the period of a strong fault depression, the basement fracture is main control factor of base level changes. The distributional rules of reservoir growth in the process of the base-level changes are pointed out .
