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.
The removal of linear interference is of great significance to improve the profile quality of marine shallow water high-resolution seismic exploration.This paper studies the characteristics of linear interfering wave in high-resolution marine seismic exploration, analyzes the basic principle of TAUP transformation to remove linear interference, Which is applied to the removal of linear interference in marine high-resolution seismic exploration.The practical processing results show that the linear interference removal effect is obvious and the signal-to-noise ratio of the cross section is enhanced by the TAUP transformed superposed profile.By comparing with FXCNS, Compared with the filtering effect of removing the linear noise, the technical method using TAUP transform to suppress the linear noise can obtain more obvious effect in high resolution seismic exploration data processing in the Bohai Sea.
