【摘要】 多子波分解是一个较新的概念,它是把一个地震道分解成不同形状的地震子波的集合,然后对子波频率进行筛选,对不同的目标重构出新的地震道,以此来提高地震分辨率,识别地层异常信息。本文以树型结构为基础,提出了全树型分解、分段树型分解、分段回归树型分解三种分解算法并取得了较好的分解效果。更多还原

【Abstract】 Multi-wavelet decomposition and reconstruction is a new concept and useful technology.It is the technology that decomposes one seismic record into severial different wavelets,and then it selects the wavelets with the specific frequency and reconstruct new seismic record according to different purpose.It can increase the resolution of seismic data and identify the anomalous information of stratum.Based on the tree structure,the paper brings forward the arithmetics of complete-tree decomposition,fractional-tree decomposition,regressive-tree decomposition and has obtained the good decomposition effect.更多还原
