伊宁凹陷衰减多次波处理方法研究

Discussion on Anti-Multiple Wave Technoogy in Yining Depression of Yili Basin

本文对伊犁盆地伊宁凹陷产生多次波的成因进行了分析 ,结合该区 2 0 0 0年宽线采集的地震资料处理过程 ,对压制多次波的方法进行了有益的探讨 ,利用拉冬域滤波方法结合内切除 ,对衰减伊宁地区多次波有明显效果 。

The origin of forming multiple waves in Yining depression in Yili basin is analyzed in this paper.Based on the detailed analysis to the geologic feature and the cause of multiple wave and combined with the wide line seismic data in Yining Depression of Yili basin in 2000.The method of pressing multiple wave is discussed.By means of filtering in Radon domain and internal muting,better processing result is got,offering effective method and reference for anti-multiples in the future.\;
