摘要
提出了油气成藏流体动力系统的概念和重力驱动型、压实驱动型、流体封存型及滞流型油气成藏流体动力系统类型的划分方案．流体动力系统类型的确定从盆地的演化史分析和流体动力特征分析两方面来进行．油气成藏主要驱动力的相对重要性在重力驱动型、压实驱动型、流体封存型系统中不同，浮力在３类系统中都重要，水动力只在前两类中重要，而热力仅在第三类系统中发挥重要作用，地应力在第一和第三类系统中重要．油气成藏流体动力系统研究对油气勘探有实质性的指导意义．
The concept of oil and gas migration and accumulation fluid dynamic systems as well as a classification of four system types, including gravity-driven flow, compaction-driven flow, fluids compartment and no_flow are presented. The determination of system types can be based on the basin evolution analysis and fluid dynamic characteristics. The relative importance of the main driving forces in oil and gas migration and accumulation is different in gravity_driven flow, compaction_driven flow and fluids compartment system types. Buoyant force is important for all the three system types. Hydrodynamics is only important for the first two system types. Thermodynamics is just important for the third system type while the stress for the first and third ones. Studies on oil and gas migration and accumulation fluid dynamic systems are essential for oil and gas exploration.
