摘要
多次波在地震勘探过程中是一种顽强的干扰波,其存在不仅会影响速度拾取的精度,还会与有效波相互干涉,影响成像精度,严重时还会湮没地质现象、误导地质解释成果。随着数据处理精度的不断提高,如何在保护有效信号的前提下压制多次波成为重要的研究课题。本文根据金家南地区多次波特点提出频率—波数域(F—K域)的压制方法,在应用中取得了很好的效果。
The multiple is a kind of stalwart disturbing wave in seismic exploration, which can not only affect the accuracy of velocity picking and imaging, but also intervene effective wave to each other, especially, can misdirect geological interpretation results due to the annihilation of geological phenomenon. With the ongoing improvement of seismic data processing accuracy, multiple suppression based on the protection of effective signals becomes an important research subject. In the paper, the method of F-K domain suppression has been brought forward according to the characteristics of multiple in Jin Jianan Area and good results have been obtained in the actual application.
