摘　　要：近年来在深部和区域地质方面所获得的新的发现进一步支持了我国近海沉积盆地经历了多期热事件的认识，近海盆地的成因与深部作用地幔柱构造不可分割，表现出与亚洲东部特殊的地质背景的相关性和统一性，多幕动力作用决定了盆地具有多个含油气系统，其中超压系统多期破裂产生并驱动的含烃热流体的多期活动成藏和重就位是基本的成藏动力学特征，而现今作为含烃流体场动态演化的一个切面，油气藏是盆地流体场中的特殊异化点，因此盆地水文系统的温、压、化学场以及成岩场的特征是判别油气藏分布的重要标志。The recognition that basins in China offshore have experienced multi-stage thermal events,is sustained further by new discoveries made in the deep and regional geology in recent years. Basins in China offshore that their origins are bound up with the deep geologic process (Mantle Plume Tectonics), are in accord with the special geologic background of East Asia. The multi-dynamic processes controlled the multi-systems of hydrocarbon in basins,in which the multi-stage activities and pool-forming and reemplacement of hydrocarbon are the basic characteristics of pool-forming dynamics. In these basins,the present patterns work as a temporal results of the active evolution of hydrocarbon-bearing fluid field,and oil and gas-pools are as special allochemical points in the fluid field. Therefore temperature,pressure,chemistry and diagenism etc. are all the important marks of estimating distribution of oil and gas pools.
