Analysis on Application Efficiency of Frequency-broadening Seismic Data in Logging Constrained Seismic Inversion
Qin Yue-shuang · Science Technology and Engineering · 2012
The resolution of seismic data inversion effects of seismic reservoir prediction,seismic inversion to broaden seismic frequency is an important step of work.This attempt to wavelet compression technology,this technology is in the post-stack seismic data directly on the extension frequency,frequency after processing the seismic data bandwidth than conventional processing seismic data high bandwidth of about 20 Hz,on the basis of comprehensive utilization of vertical resolution of logging data and seismic lateral sampling point concentrated advantage,seismic inversion well,after 26 port calibration test,sand body prediction results coincide with higher levels,illustrate the extension frequency after processing the seismic data to a certain extent improve the seismic resolution.
