摘要
研究表明,三维叠后去噪对断层有较大的影响,并且可以导致地质解释的错误。介绍了常规三维叠后去噪和三维共反射面元叠加(CRA3D)对小断层和断距为一个时间周期的断层的影响实例,指出三维共反射面元叠加(CRA3D)对断层的影响小,是三维地震资料处理断层保护的有效叠后去噪方法。
Study showed that3D poststack noise suppression has more effects on faults,which can result in mistakes of geological inter-pretation.This paper presents a case that conventional3D poststack noise suppression and3D common reflection area stack(CRA3D)affect small faults and faults with a time cycle of fault throw.It is pointed out that CRA3D is an effective method for poststack noise suppression and fault protection during3D seismic data processing.
