An Effective Method of Velocity Analysis
LI Qing-chun · Journal of Earth Sciences and Environment · 2008
How to obtain high resolution P-wave velocities is a key in the seismic data processing.Based on conventional velocity analysis,the bootstrap procedure introduced is a computer-intensive technique for assigning measures of accuracy to statistical estimates.The method can greatly improve resolution of the velocity spectra.The tests of synthetic model and processing of real data show that this method has high resolution and robust stability,which may increase the calculating accuracy of the velocity spectra.Therefore,the picking velocities can ensure the latter processing.
