摘要
从构造、沉积、成藏相互关系进行分析的角度,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。
This paper established the controlling effect of apposition tectonics in Jiyang depression on deposition and hydrocarbon accumulation, and suggested that the apposition tectonics is favorable to hydrocarbon generation, migration, accumulation and storage. After the discovery of large and medium hydrocarbon reservoirs sequence stratigraphy theory, hydrocarbon system theory and hydrocarbon accumulation dynamics theory should be fully applied in Jiyang depression to study the controlling effect of apposition tectonics' development and evolution on sedimention.
