| 摘 要： | 本文开展了薄层的叠前地震属性的分析研究,定性分析了薄层厚度对叠前地震属性的影响.薄层叠前正演及分析结果表明,薄层厚度对叠前反射振幅的调谐效应也很明显,并影响了叠前属性的计算.利用薄层厚度对叠前属性的调谐效应可以确定出薄层的厚度.对于小于调谐厚度的薄层,提出应用AVO属性与层厚的近似关系进行层厚估计的思路.

| Abstract: | This paper studied pre-stack seismic attributes of thin-layer,and qualitatively analyzed the thin-layer thickness on the impact of pre-stack seismic attributes.The forward modeling of the thin-layer and analysis results show that the tuning effect of pre-stack reflected amplitude caused obvious,and thin-layer thickness affected the calculation of pre-stack attribute.Using the tuning effect of pre-stack attributes resulted by thin-layer thickness to determine the thickness of the thin-layer.For the thin-laye... |
