文章从构造、沉积、成藏相互关系的角度, 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时空匹配关系, 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。

Investigated from the aspect of relationship among tectonic movement, sedimentation and reservoir-forming, the paper demonstrated systematically the action of contemporaneous structure controlling the sedimentation and reservoir-forming. Results show ed that the movement of contemporaneous structure is good to reservoir-forming in several ways, such as hydrocarbon generation, migration, accumulation and preservation. Analysis showed that after the discovery of big-middle scaled oil-gas reservoir in Jiyang depression, the theories of sequence stratigraphy, petroleum system and kinetics of reservoir-forming should be utilized at their most to enhance exploration effect.The theories mentioned above can be used to study the control action of contemporaneous structure to the process of sedimentation, entrapment-forming, reservoir-forming and spatio-temporal matching feature of source-reservoir-caprock. Study on contemporaneous structure is converting from qualitative method to quantitative method and temporal method. Dynamical mechanism is emphasized in the study, and simulation of quantitative process is perfecting as well.
