摘要
Abstract
The whole seismic data processing needs velocity analysis,and the precision of velocity analysis impacts the final quality of seismic imaging. When the fold is not high or the S/N is low, the energy group of seismic velocity spectrum is scattered. In this condition, multi-bin array is often used to increase the data quantity of velocity analysis. By analyzing the influence of data quantity and the data bin size, we proposed to adopt ellipse data bin array to optimize the data quantity participating in velocity analysis and eliminate the influence of the anisotropy of the data away from central point on the precision of velocity analysis. By this means, the precision of velocity analysis in middle-deep layers can be improved. The method was applied to the actual data processing and the precision of velocity a-nalysis was increased to some degree.关键词
