方向性滤波去噪方法及其应用
摘要
Abstract
The current seismic noising cancelling methods are mostly data processing by means of reading the seismic data trace by trace without considering the layer structure information. Orientation filtering method can filter data along seismic events. So, it can improve the SNR of seismic signal more effectively, enhance the continuity of seismic events and show sequence internal model clearly. Firstly, seismic events direction information is estimated by using the gradient structure tensor. Secondly, orientation filter is designed depending on the direction information. Finally, the proposed filter is applied in real seismic data processing. Model and real data application shows that this method can provide high quality seismic data for seismic data processing, and thus has a better practical application value.关键词
