摘要/Abstract

摘要：

文章基于叠前深度偏移地震成像分析, 结合前人重磁反演等地球物理资料成果, 对中沙海槽盆地东北部结构构造进行探索研究。研究表明: 中沙海槽盆地东北部发育新生代地层, 厚度在1500~2500m之间, 地层层速度为1500~ 3500m·s^-1, 不存在中生界沉积层, 盆地基底为海山或前寒武系基岩及岩浆岩隆起。中沙海槽盆地新生代陆源海相烃源岩丰富, 盆地新生界地层厚度大, 盆地凹陷、断裂发育, 具有一定的油气勘探潜力。

关键词: 深度域地震成像, 中沙海槽盆地, 盆地结构构造

Abstract:

Based on analysis of the seismic images from prestack depth migration, combining previous results inverted from geophysical data, e.g., gravity and magnetic inversions and so on, we investigate the structure of the northeastern Zhongsha Trough Basin in the South China Sea. The results indicate that the Cenozoic strata are developed with a thickness of 1500~2500 m, and the stratum velocity is 1500~3500 m·s^-1. There is no Mesozoic sedimentary layer. The base of the basin could be seamount, Precambrian bedrock, or magma uplift. The abundance of Cenozoic terrigenous marine source rocks, the thick layer of the Cenozoic strata, and well-developed basin depressions and faults all suggest that the northeastern Zhongsha Trough Basin has a certain potential for oil and gas exploration.

Key words: depth-domain seismic imaging, Zhongsha Trough Basin, basin structure
