摘要
线性干扰的去除对于海洋浅水高分辨率地震勘探剖面质量的提高具有重要意义.本文对海洋高分辨率地震勘探线性干扰波特性进行了研究,分析了TAUP变换去除线性干扰的基本原理,并将其应用于海洋高分辨率地震勘探中线性干扰的去除.实际处理效果表明,经TAUP变换处理后的叠加剖面,其线性干扰去除效果明显,剖面信噪比得以提升.通过与FXCNS、多道倾角滤波去除线性噪音效果对比,使用TAUP变换压制线性噪音的技术方法在渤海地区高分辨率地震勘探资料处理中可获得更为明显的效果.
It is important to attenuate the linear noise for the improvement of the high resolution seismic exploration profile.This paper does a research on the character of the linear noise and analyses the principle of TAUP transform which is used to attenuate the linear noise in the high resolution seismic exploration.The processing result shows that the stack profile with TAUP transform is better than that without TAUP transform which S/N ratio improves.The TAUP transform technology is also compared with FXCNS and multichannel dip filter,the result shows that TAUP transform is more suitable for the high resolution seismic exploration in Bohai Sea district.
