断陷盆地油气聚集模式及其动力学特征

以济阳坳陷为例 ,从构造、地层、沉积及油气源、圈闭、储层、油气运聚、油气成藏等方面分析了断陷盆地不同二级构造带油气聚集的特点和分布规律 ,总结出了主要的油气聚集模式及其与油气藏 (田 )规模的关系 ,并探讨了它们形成的受控因素及动力机制。研究表明 ,低凸式、陡坡式、中央隆起式油气聚集带是济阳坳陷最有利和最重要的复式油气聚集带 ,洼陷式、凸起式油气聚集带是济阳坳陷进一步探索的重要领域

ACCUMULATING MODELS OF PETROLEUM AND THEIR DYNAMIC CHARACTERISTICS IN FAULTED DEPRESSION BASIN

Formation characteristics of oil and gas reservoir, including structures, stratigraphy, deposition, source rock, traps, reservoir, migration and accumulation, are analyzed and compared for different secondary structural zones in Jiyang Depression. Six representative oil and gas accumulating models can be recognized, and their controlling factors as well as dynamic mechanism are also disscussed. The study shows that three types of oil and gas accumulating zones, including low heave, steep slope and central arch, are important and favorable explorating realm, and low\|lying as well as heave oil and gas accumulating zones need to be investigated further.
