【Abstract】 A study of signal spatial structures from seismic and logging data provides the varigram model for 3 D geologic model building. An efficient stochastic modeling method is proposed in this paper considering characteristics of complex reservoir geology in China. The seismic stochastic inversion based on the wave equation is developed and seismic impedance is obtained. Information from high confidence data sources is incorporated in the inversion by using information fusion algorithm. The confidence of inverted results is analyzed with probability statistic methodology. High resolution imaging of impedance is achieved.更多还原
