变视速倾角滤波方法的应用

Application of varying apparent velocity filtering method

通过滤波来压制噪声、加强有用信号是地震数据处理的重要任务，传统的时变滤波一般是采用分段时窗方法．在ＣｌａｅｒｂｅｕｔＪＦ方法的基础上提出一种现速度逐点变化的滤波方法，并应用干地震勘探数据处理．

Suppressing noise and enhancing useful seismic signal by filtering is one of the important tasks of seismic data processing. The piecewise time-windows method is adopted by conventional time-variant filtering. Based on the method proposed by Claerbout J F, in this paper, a filtering method of varying apparent velocity point -to-point is developed and applied in seismic data processing.
