摘要
黄河三角洲冲积平原区近地表岩性变化剧烈,重点从黄河三角洲浅层沉积模式分析了岩性分布差异,统计了不同岩土的塑性、应力、压缩特性规律,探索了利用这种岩性特征差异识别岩性的方法,为地震采集提供准确的激发层段,为地震资料处理提供精细的静校正量。
The near-surface lithology of alluvial plain area in Yellow River delta always changes greatly.This article mainly analyzes the lithological distribution differences from the aspects of superficial depositional mode of the delta,sums up the plastic property,stress and compression characteristics of different lithological layers,and gives methods of distinguishing lithologic characters according to the lithological differences,to provide correct excitation layer for seismic acquisition,and accurate static correction for seismic data processing.
