Abstract:Improving both signal/noise ratio and resolution of seismic data is a vital subject in hydrocarbon geophysical exploration.I recommend three new deconvolution methods(waveform-revised deconvolution,multitrace-statistical wavelet deconvolution and spectrum pattern deconvolution) and their corresponding procedures.In the waveform-revised deconvolution,the sum of all noises is taken as a com- plicated linear filtering system,which is then considered in a deconvolution model.In the multitrace-statistical wavelet deconvolution,one separate algorithm is used to guarantee the accurate phase spectrum of inverse wavelet.The spectrum pattern de- convolution is poststack deconvolution method and involves a parallel filtering algorithm. Real data processing shows that the methods make seismic section have high signal/noise ratio and good resolution,and bring particularly satisfactory results in processing low signal/noise ratio seismic data from complicated areas.
