- W2353791428 abstract "For seismic data processing,improving calculation efficiency and seeking well treatment effect were the constant goals of geophysicists.The improved empirical mode decomposition(EMD) in F-X domain(F-X-EMD) was mainly introduced for noise suppression.Firstly,the seismic signals were decomposed into a series of intrinsic mode functions(IMF) after they were transferred into F-X domain removing the first component,other components of IMF were filtered by wavelet threshold filtering for noise attenuation.Furthermore,in order to perfect the calculating efficiency of improved F-X-EMD,the distributed parallel algorithm with higher computational efficiency and accuracy was presented.The numerical simulation results show that compared with prediction of filtering in F-X domain,the improved F-X-EMD is more effective in random noise attenuation and coherent noise suppression.Finally,the real seismic data results show that the new method has effectiveness and superiority in seismic data processing analysis." @default.
