摘要
吐哈盆地原始资料各种噪音发育,特别是强面波干扰,大部分资料有若干组不同视速度的强线性干扰。如果叠前去噪不理想,对资料的后续静校正,速度分析,偏移成像处理有很大影响。F-K滤波是一种很好的迭前去噪手段,通过分析研究,总结了一套F-K滤波的处理流程,并取得了很好的效果。
The original seismic data of Tuha basin riches in all kinds of noises, especially strong surface wave. Most data has several groups of severe linear disturbance. Low quality pre-stack noise removing will have significant effect on the consequent static correction, velocity analysis and migration imaging process. F-K filtration is a good method for pre-stack noise removing, but if it is not used properly, and the ideal conditions of the F-K filter are not sufficed, the result of filtration will deviate considerably. Through analyses of all factors affecting F-K filtration, a set of working flow for it has been summarized, and obtained good result in application.
