摘　　要：在地震数据处理过程中,“三高”的地震资料处理原则至关重要,可为后续地震资料解释以及油气储层的预测提供可靠依据和重要保障.所谓“三高”即高信噪比、高保真和高分辨率.其中,地震数据去噪部分成为地震数据处理的首要任务.对于地震资料去噪方面,前人已经做了大量的工作,尤其是关于叠后资料的去噪已经有了很多成熟方法.以自适应面波衰减、三维相干噪音压制以及异常振幅压制的常规去噪技术,针对地震资料叠前去噪常规技术方法进行探讨与研究.In the process of seismic data processing,"three high"seismic data processing principle is very important,which can provide reliable basis and important guarantee for subsequent seismic data interpretation and oil and gas reservoir prediction.The so-called"three high"means high signal-to-noise ratio,high fidelity and high resolution.Among them,the seismic data denoising part becomes the primary task of seismic data processing.For seismic data denoising,predecessors have done a lot of work,especially for post stack data denoising has many mature methods.In this paper,the conventional denoising techniques of adaptive surface wave attenuation,three-dimensional coherent noise suppression and abnormal amplitude suppression are used to discuss and study the conventional techniques for seismic data pre-stack denoising.
