| 摘 要： | 介绍了成藏动力系统中流体的 3个来源 ,即沉积流体、自源流体和深源流体 ;推动流体运动的五种动力 ,即盆地深部的热动力、自源动力、重力流、浮力和毛细管力叠加产生的作用力、构造动力。分析了在成藏动力系统中这几种动力的作用机制。指出深部热动力控制了成藏动力系统的温压场和成藏作用的时空展布 ,沉积盆地中自源动力控制烃源岩生排烃过程 ,而油气在自源动力的压实流、重力流、浮力以及毛细管阻力叠加形成的流体势控制下进行二次运移、聚集和成藏。构造动力既是圈闭形成分布和油气运移聚集的控制因素 ,又是导致油气藏破坏、油气再次运移、聚集的重要作用力

| Abstract: | Three sources of flows and five kinds of power that make the flows move in migration\|accumulation dynamics system are introduced. The flows in the system include sedimentation fluid, self\|original fluid and deep\|original fluid. The five kinds of power include deep thermodynamic power, self\|original power, gravity flow, acting force produced by buoyancy and capillary resistance and tectonic power. This paper also analyses the acting mechanism of these powers in the migration\|accumulation dynamics system. Deep thermodynamic power controls the temperature and pressure field in the system, and controls the space\|time distribution in the pool\|forming action. The self\|original power controls the hydrocarbon\|generating and expulsion process in the sedimentary basins. Other three powers control secondary migration and accumulation of the hydrocarbon. The tectonic power controls the formation and distribution of petroleum traps, migration and accumulation of the hydrocarbon, and destroys the pools and makes the petroleum migrate and accumulate again. |
