Abstract
Based on offshore earthquake data collected by our company,geological and geophysical model was built to fully analyze the effect of wavelet transform,empirical mode decomposition processing and EMD wavelet threshold de-noise on offshore earthquake data processing,and discuss the wavelet threshold de-noising method based on EMD,which played an important role in the suppression of noise,the improvement of signal to noise ratio (SNR)and resolution during shallow sea seismic data processing. This method has a positive significance in refining seismic data and achieving fine layer classification based on the geophysical results.关键词
