| 摘 要： | 大油气藏之上普遍存在的剥蚀面与油气藏之间的关系正在受到油气地质学家的关注。剥蚀意味着减压，将会导致下伏饱和介质（砂体）回弹。砂体回弹可以为地层流体提供更多的可容空间和造成地层低压，从而提供流体运秽的动力和油气聚集的场所。因此，地壳抬升剥蚀卸压导致砂体回弹从而泵吸油气成藏很可能是一种油气成藏的新机理。

| Abstract: | In large hydrocarbon reservoirs, great attention is being paid by geologists on the relationship between the widespread erosion surface and the reservoir erosion means pressure drop, which will result in rebound of underlying saturation medium(sandbody), by which more space for formation fluid is provided and low pressure in formation is induced, therefore power for fluid migration and space for hydrocarbon accumulation are provided. Thus pumping oil and gas accumulation caused by sand rebound from tectonic uplifting and pressure releasing from erosion is possibly the new mechanism of hydrocarbon accumulation. |
