| Abstract: | In this paper, properties of sample function of fractional Brownian motion and Gaussian noise to analyzing the sequence from No. 57 well log in LenNan,JiLKa are applied.lts reflection trace and velocity trace are approximated by a fractal curve with fractal dimension 1. 76 and 1. 10 respectively,and their spectral density are approximate to f0.52 and f-0. 8 respectively. Fractal properties and other related properties of local fractional Brownian motion and Gaussian noise,geostatistical method and improved deconvolution to analyzing seismic signals in JILAKE. That sequence of reflection variation is a fractal curve of local fGn type with fractal dimension (2-Hk) for every seismic trace CDP k. |
