摘要
随着油气资源开发向深水区发展,迫切需要采用一定的方法去了解块体运动的特征以及分析块体运动对深水油气资源开发的可能性。本文阐述了东海陆坡块体运动地形分析方法以及多种数据处理技术的使用。多波束测深系统为人们提供了直观的海底地貌形态特征,地层剖面仪系统能探测海底以下沉积物性质和结构的变化。GIS、Fledermaus、Delph等软件系统可以定量分析海底微地貌形态特征。
As interest in developing offshore resources increases, so too does the need to find some methods to characterize submarine mass movement and determine the probability that these events will affect new develop, ments. This paper presents a detailed morphological analysis integrating bathymetric and acoustic profiles can help to clarify the underlying mechanisms which may lead to mass movements in the continental slope of the East China Sea. Multi-beam sounding system has provided us with visual submarine topography characteristics, and Sub-bottom Profiler system can probe the property and structure of sediment below the seabed. Several data processing technologies, such as GIS, Fledermaus and Delph, are used in conjunction to quantitatively analyze micro-geomorphology of the seabed.
