A high-resolution procedure of low SNR data for North Ordos bason
|
Abstract:
The complexity of the seismic geologic conditions in North Ordos basin is caused by low SNR and low resolution of the initial seismic data, The antecedent data of the seismic reservoir and the prognostic gas bearing result have not met the needs of exploratory development nowadays. Considered the low SNR data of North Ordos basin, a practical high-resolution processing method for this area is presented in this paper. It includs solution of static correction and noise suppression, applying deconvolution, fine velocity tuning, highprecision NMO correction and stacking. The higher resolution of the seismic data has been obtained on the premise of high SNR.
