摘　　要：作为西太平洋最大的边缘海,南海是地质科学研究和资源勘探开发的热点.本文整理和分析了近年来南海深部过程、洋盆扩张、形成动力学机制及其与含油气盆地耦合关系等研究成果.结果表明,洋盆扩张作为南海形成演化的核心问题,扩张模式与年代、动力学机制以及深部过程均存在较大争议.但普遍认为南海是在伸展作用下,伴随着大规模的岩石圈减薄而形成的.南海含油气盆地广泛发育,均认为其形成演化主要受南海深部动力过程作用的控制,但关于南海深部过程对盆地和油气分布规律的控制作用等基础问题,目前的研究结果尚不能准确回答它们之间的耦合关系.基于前人研究工作,结合本文开展的南海深部构造界面反演,初步建立了南海深部过程及与沉积盆地耦合模型.在此基础之上,建议开展更为细致深入的综合地球物理研究,确定南海深部结构及构造,构建南海深部演变过程,结合南海周缘含油气盆地分布及性质,明确南海深部过程对含油气盆地的控制作用,对比分析南海盆地的油气资源分布特征,从而阐明油气资源与深部构造及过程的关系,以期更好的理解南海深部过程及其对含油气盆地的控制作用.As the largest marginal sea in the western Pacific,the South China Sea is the hotspot of geological scientific research and nature resource exploration and development. In this paper,we systematically review the recent progresses of the deep processes,ocean basin expansion and the dynamics of formation of the South China Sea, and their coupling relationships with hydrocarbon basins. The result suggests that the expansion mode and age,as well as deep process dynamic mechanism of the South China Sea are all considerable controversy. But most researchers generally agreed that the South China Sea was formed in the background of extended actions,along with large-scale lithospheric thinning. In addition,petroliferous basins are widely developed in the South China Sea,whose formation and evolution are mainly controlled by the deep process of the South China Sea. But the current research results cannot yet be accurately answered the coupling relationship between them. Based on the previous research and combined with deep structures surfaces inversion in this paper,we propose a preliminary model of the deep processes and their coupling relationships with the petroliferous basins in the South China Sea. In order to understand deep process and its controls on the distribution of the petroliferous basins,we suggest carrying out a deeper comprehensive geophysical study to specify the tectonic and structure, construct the deep processes of the South China Sea,and combined by the distribution of the petroliferous basins to make clear the controlling effect.Furthermore,based on comparative analysis of the oil and gas resources distribution,clarify the relationship between the oil and gas resources and the deep structure and processes in the South China Sea.
