地震勘探波场分离与去噪处理思路

地下地质结构的复杂性造就了地震波场的复杂性,有效信号与干扰噪声相伴产生,如果不能很好地把它们彼此分离开来,就不能准确、有效地提取地下的地质信息,也就失去了勘探的目的和意义。因此,在地震资料处理过程中,有效信号的提取与干扰噪声的衰减显得至关重要,是地震资料高分辨率、高保真度处理的前提和基础,同时也是难点技术之一。针对地震勘探自身的特点和目前已有的地震资料处理方法和技术,阐述了一些地震波场分离与去噪处理的心得和思路。

Processing Mentality with Wave Field Separation and Denoise for Seismic Exploration

The complexity of the structure of the subsurface geology has brought up the complexity of seismic wave field,which make desired signal and interference noise accompany production.If it cannot be separated from each other,the underground geological information would not be acquired accurately and effectively,also there aren’t any the exploration goal and the significance.Therefore,in the seismic data treating processes,the desired signal extracting and interference noise attenuation appear very important,which is the premise and the base for seismic data high resolution and high fidelity processing,simultaneously,which is also one of difficult technologies.In view of seismic exploration own characteristic and the present existing seismic data processing method and technology,this paper elaborated some seismic wave field separation and denoising processing attainment and the mentality.
