摘要
Abstract
Because of the topography characteristics and the complicated surface seismic geological conditions of the exploration area in Ordos Loess Plateau,the seismic data acquired have strong multiple sets of linear noise.The elimination of the linear noise and the im⁃provement of SNR of seismic signal is one of the key problems in seismic data processing.In this paper,the authors conducted a compre⁃hensive analysis and study of all types of linear noise as well as the multiple sets of surface waves. Based on the linear noise's linear characteristics,dip features and coherence properties, the authors used the addition⁃subtraction method to remove the linear noise. A comparative analysis shows that this means is a high⁃fidelity method that has a strong capability for suppressing linear noise and impro⁃ving the quality of data processing,thus showing a significant effect.关键词
