| 摘 要： | 本文从9个方面阐述了中国沉积盆地的复杂性，主要表现为：①数量多，规模小，分布广；②盆地类型多样；③多期盆地叠合和盆地复合现象普遍；④陆相沉积盆地的复杂性；⑤断层数量众多，活动强烈；⑥后期改造强烈；⑦岩浆活动频繁，分布广泛；⑧充填速率较快，沉积中心多有迁移；⑨地热场空间不均。在此基础上，对中国沉积盆地复杂性的成因进行了剖析，指出中国特殊的大地构造位置，陆块面积小、稳定性差，活动带规模大、活动性强，复杂的板块构造格局和构造演化历史是造成中国沉积盆地复杂性的根本原因，并造成了中国沉积盆地与众不同的油气赋存特征。

| Abstract: | The complexity of sedimentary basins of China is mainly manifested in the following nine aspects:(1)large number,small size and wide distribution;(2)a great variety of basin types;(3)prevalence of the phenomenon of multi-stage basin superimposition and compounding;(4)dominance of continental sedimentary basins;(5)occurrence of numerous,very active faults;(6)strong reworking in the late stage;(7)repeated and extensive magmatic activities;(8)rapid filling rate and migration of most depocenters;(9)inhomogeneous space of the geothermal field.On the basis of this analysis,the authors analyze the origin of the complexity of sedimentary basins of China and point out that the special tectonic position,small and less stable continental block,large-scale and active mobile belt and complex plate tectonic framework and tectonic evolutionary history are the root-causes for the complexity of sedimentary basins of China and caused these basins to have their distinguishing characteristics of petroleum occurrence. |
