High Resolution Processing Method for 3D Seismic Data
-
Abstract
The method is to broaden the frequency band of effective signals and raise the signal -to -noise ratio in wide frequency band. According to the method and large amount of ana1ysis and experiment, a processing procedure is dcsigned which consistS of prestack deconvolution conbination, automatic restraining interferencc of large irnplitude, velocity analysis with high accuracy- etc. Through utili7ation of this method, the processcd data show that thc dominant frequency is doublcd .Comparcd with conventional processing method,fault position is accurate and the signal - to - noise ratio higher.
