基于相关原理的噪音压制保幅性评价方法
|
摘要
地震资料处理中的噪音压制是将有效信号与噪音分离的过程,噪音压制技术有很多,但是对噪音压制过程中的质量控制和保幅性评价一直没有很好的方法。研究噪音压制后的信号分量与噪音分量的互相关函数,从中分离出噪音分量中可能包含的部分信号的互相关能量,得到在噪音压制过程中是否存在噪音压制过量而伤害到信号的保幅性评价方法。应用合成数据和实际地震资料验证了方法的有效性,该方法可以对噪音压制过程做相对量化的分析评价,适用于保幅、保真地震资料处理噪音压制过程的质量控制。
Noise suppression in seismic data processing is a procedure to separate noise from seismic data.There are many methods to suppress noise,but still there is no very effective technology to monitor quality and evaluate the characteristic of amplitude preservation in noise suppression process.We studied the crosscorrelation function of the signal component and the noise component,and separated the cross-correlation energy of the residual signal in the noise component from it,then established a method to evaluate whether excessive noise suppression had hurt the amplitude characteristic in noise suppression process.Both synthetic data and real seismic data verified the validity of this method.This method can be used to quantitatively evaluate the noise suppression process,and it is suitable for quality control in amplitude and fidelity preservation seismic data processing.
