Determination method of deconvolution parameters and processing method of seismic data

The invention provides a deconvolution parameter determination method and a seismic data processing method, and belongs to the field of petroleum and natural gas seismic exploration. The deconvolution parameter determination method comprises the following steps: selecting N test parameter values for deconvolution parameters of a target exploration area, respectively performing first reverse selection processing, second reverse selection processing and third reverse selection processing, reversely selecting N-1 test parameter values according to the reverse selection results of the first reverse selection processing, the second reverse selection processing and the third reverse selection processing, and determining the deconvolution parameters of the target exploration area according to the reverse selection results of the first reverse selection processing, the second reverse selection processing and the third reverse selection processing. And determining a deconvolution parameter, wherein N is an integer and
