摘要
定量地震地貌学以三维地震数据为基础,通过对地貌特征参数的定量分析来了解盆地历史、沉积过程和填充构架,在沉积体系定量分析和储层表征方面为一新方向.其主要研究内容包括系统地质研究、地震属性分析、地貌特征定量分析、沉积单元交汇分析和沉积体系影响因素研究等五方面,核心为多数据融合及沉积单元形态定量数据的利用.定量地震地貌学在冲积河道、三角洲、浊积水道、水下扇储层特征及结构研究方面已取得较大突破,在地层沉积定量研究、储集体规模预测方面具有较大优势和前景.
Quantitative Seismic Geomorphology （QSG） is a new direction in quantitatively analyze of sedimentary system and reservoir characterization, which imaged in 3-D seismic data for the purposes of understanding the history, processes, and fill architecture of a basin. Through analysis of definition and characters of the contents, methods and techniques of QSG are illustrated, such as systematic geologic research, seismic attribute, geomorphologic parameters, sedimentary elements and influences analyze. The keys of QSC- are data fusion and utility of morphometric data. Advances and unique of QSG are analyzed by the applications of debris channels, alluvial channels, submarine fans, delta, et al. This subject has advantage in the depositional system quantitatively research and reservoir body volume measurements by the integration of high resolution seismic image, outcrop sedimentlogy, computer simulation and sequence stratigraphy.
