几种简单实用的多次波去除方法及其应用
|
摘要
多次波衰减是地震资料处理中的老问题,多次波的存在严重影响地震剖面成像的真实性和可靠性,干扰地震资料的解释,所以,在叠前应对多次波加以有效的消除,提高资料的品质和精度。而目前,多次波理论方面的研究及成果相当多,但对于实际生产有时却无能为力。因此,本文意在从原理和可操作性上,介绍几种在实际生产中既简单实用又省时有效的多次波去除方法及其应用效果,主要介绍了数据一致性预测反褶积、R adon变换、利用速度扫描工具及内切除等四种多次波去除方法及其应用效果。以提高资料的处理质量和效率。
Suppression of multiple waves is an old problem in seismic data processing.Mutiple waves have serious effect on the facticity and reliability of seismic profile.This effect its interpretation.Therefore,some measures should must be done to suppress multiple waves.At present,there are many theories and achievements about multiple waves.But sometime they are useless in practical proceesing.So,several practical methods of multiple waves suppression are introduced in the paper.These methods are simple and available.There are four methods: consistency pre-deconvolution,Radon transform,velocity scan and inside mute.These methods can improve quality and efficiency of processing.
