Title: Quality control methods of synthetic seismograms
Abstract: Quality control(QC) of synthetic seismograms is the key for subtle horizon interpretation.Based on the analysis of the synthetic seismogram principle,this paper suggests three steps of quality control:① exact calculation of reflect coefficients from well logging data;② extracting a wavelet which is consistent with seismic well side trace in spectrum,waveform and phase;and ③ based on high precision velocity field,matching synthetic seismograms with seismic well side trace according to wave group,waveform,amplitude,frequency and phase characteristics.Here a full suite of QC methods is presented,which advances the precision of synthetic seismograms and meets the needs of horizon interpretation.
