摘要: 阐述了油气成藏流体动力系统分析的基本原理，把油气成藏流体动力系统分为重力驱动型、压实驱动型、滞流型和封存型四种类型。结合国内外的研究实例，分析了不同类型流体动力系统油气藏形成和分布的规律，强调在不同类型的流体动力系统中，油气藏形成的机理不同，在成藏动力学研究中有不同的侧重点。加强重力驱动型和封存型流体动力系统动力系统油气成藏条件研究对我国南方海相盆地和其它勘探程度较高的盆地深部的油气勘探具有重要意义。Abstract: Principles of oil and gas formation fluid dynamic system analysis are briefly described. Fluid dynamic systems are classi fied into four types, including gravity-driven flow, compaction-driven flow, fluid com-partment and no-flowones. Oil and gas pools formation and occurrence for each type are analyzed, along with case studies. It is emphasized that for different types of fluid dynamic systems, the mechanism of oil and gas pools'formation is different, and then, studies on these different types of fluid dynamic systems should have different focus. Finally, it is indicated that the studies on gravity-driven flow and fluid com-partment system types are respectively important for petroleum exploration in the marine basins of southern China and in the deep parts of the basins relatively maturely explored in China.
