Abstract: One of the important means of improving seismic resolution is deconvolution. There are many realizations of the deconvolution, wavelet deconvolution, impulse deconvolution, predictive deconvolution to name but a few. These deconvolution methods have their advantages and disadvantages.In case of high resolution seismic data processing thesemethods fail to meet requirements on seismic resolution. This paper described a frequency domain surface consistent deconvolution approach. Firstly spectral analysis and spectral decomposition were carried out on the seismic record, and a deconvolution operator was designed. Then the seismic data were deconvolved in common shot point domain and common receiver domain, respectively. The method can widen the spectrum, narrow the seismic wavelet, as well as output zero phase wavelet by rectifying the phases of the seismic data, which leads to greatly improv ment of the seismic resolution.Satisfactory results have been reached by applying the method to the 3-D data in Che22 and other survey areas in Shengli Oilfield.
