【摘要】 地震资料的去噪,在处理中是非常重要的内容。随着勘探技术的进步,地球物理可以用于去噪的方法越来越多。目前去噪效果相对较好的是小波变换法。小波变化以其独特的时频特性被广泛的使用于地震资料的去噪中。与以前的频率滤波相比,其优越性是可见的。本文简要介绍了小波函数以及用于地震去噪的小波变换的一些方法,并且结合实际来对小波去噪进行了介绍。更多还原

【Abstract】 Seismic data noise attenuation is a very important part of seismic data processing. With the advancement of exploration techniques,more and more geophysical methods can be used in noise attenuation. Currently the wavelet transform is relatively a better methods.Wavelet transform are widely used in seismic data noise attenuation with its unique time-frequency characteristics. Compared with the previous frequency filter,it is visible superiority.In this paper,we briefly introduces the wavelet function as well as the methods of wavelet noise attenuation,then combined with the realities of wavelet noise attenuation was introduced.更多还原
