The Seismic Imaging Data Processing Method Based on Empirical Mode Decomposition

摘要

Because of the abnormal morphology of underground are generally more complex,the seismic imaging profile by using time domain to identify abnormal body is very difficult.Using empirical mode decomposition method to decompose the seismic imaging profile,it could obtain the intrinsic mode function pictures with different frequencies from high to low.Intrinsic mode function represents the local detail information of signal in time domain.It provides more reference information for the processing and interpretation of seismic imaging profile.Examples show that,the seismic data processing method based on empirical mode decomposition can suppress random noise and improve the seismic imaging data interpretation precision and accuracy.
