中文摘要：

在深海多缆、长拖缆地震勘探的各种噪音影响中,多次波对深层的有效反射影响难以消除.笔者介绍了一种高分辨率各向异性Radon变换方法,在Radon变换积分路径中增加非椭圆率eta参数,将传统Radon变换积分曲线由慢度、偏移距两参数改为慢度、偏移距及非椭圆率三参数,更好地刻画了长偏移距下反射非双曲时差.通过对某海域实际采集的多缆长偏移距地震数据进行压制多次波处理,与传统方法相比取得了较为理想的效果,为后续深层构造成像提供了基础数据.

英文摘要：

In seismic exploration using multiple long streamers in the deep sea,the multiples damages the deep effective reflection and is difficult to remove the multiples.The authors introduce a high-resolution anisotropic Radon transform.This method brings in one more parameter of non-ellipticity eta into the traditional Radon transform,and changes the integral of two parameters （slowness and offset） to three parameters （slowness,offset distance and non-ellipticity）,which enables better capacity to characterize of the time difference in non-hyperbolic reflection under long-offset conditions.Satisfactory results are obtained through suppressing the multiples in field data of multi-cable long-offset seismic waves.The processed data are conducive to the subsequent imaging of deep structure.
