Study of seismic wavelet processing method in two step deconvolution

WANG Xi-wen,HU Zi-duo,TIAN Yan-can,WANG Hong-qi,WANG Shu-jiang,Xiao Ming-tu,Ma Jian-hua(Northwest Subsidiary of Research Institute of Exploration and Development,PetroChina,Lanzhou 730020,China)  
Facing data characteristics of seismic processing to merge 3-D seismic data from 3 area in Zhun Ge-er Basin and 2 area in San Han-tala Depression,according to purpose of seismic processing and geology,seismic wavelet processing method to merge 3-D seismic data from multi-area is put forward in this paper.It is included that two deconvolution in the method: surface consistent deconvolution to widen frequency band consistently;phase correction deconvolution to obtain consistent phase from different vibratory source.In order to gain steady operator of phase correction deconvolution from poststack seismic trace(signal-to-noise ratio in poststack seismic trace is higher in prestack seismic trace),phase correction deconvolution will be used to prestack seismic trace for phase correction.
