Analysis on Statistical Characteristics of Reflection Coefficient and Its Application in High Resolution Seismic Data Processing
Man Yi-zhi · Journal of Oil and Gas Technology · 2013
The conventional seismic data process methods for high resolution assumed that reflection coefficient series obeyed Gaussian white noise.The statistical analysis was conducted on real reflection coefficient series of well logging data from color and probability distribution,it was considered that the amplitude spectrum of real reflection coefficient series tended to be blue,and its probability density was more close to non-Gaussian random distribution.Based on the experimental results,two important parameters describing color of reflection coefficients are calculated by fitting well log data,then they are used to compensate the color of real seismic data.Not only is the resolution of seismic data enhanced,but also the consistency of seismic data and seismogram from well data is improved.
