Wavelet Processing Technology and Application of Marine Spark Source Seismic Datav
Compared with the traditional air gun source in marine seismic exploration,marine electric spark source generates multiple pressure pulses during the excitation process due to its acoustic characteristics.At the same time,due to the interference of ghost waves in ma-rine seismic exploration,electric spark source wavelet has more sidelobes,limiting the band-width of seismic wavelet and reducing the resolution of seismic data.The wavelet processing of electric spark sources generally uses deconvolution,but due to its simple technology can-not effectively solve the problem of complex electric spark source wavelets.This article uses ghost wave suppression technology,tau-p domain prediction deconvolution technology,and zero phase transformation technology to process electric spark source wavelets,solving the problem of irregular waveform of electric spark data wavelets,which has a good suppression effect on ghost wave effects,restoring the wavelet frequency band of the electric spark source,obtaining broadband seismic data,improving the resolution of seismic data,enric-hing low-frequency information and improving the recognition ability of event events.
