N2 - Extended elastic impedance (EEI) inversion is a kind of seismic exploration technology for analyzing and identifying lithology and reservoir by amplitude variation with offset. Compared with the conventional inversion, extended elastic impedance is more sensitive to the reservoir and hydrocarbon. This paper takes P1x1 and P1s2 in A Area of North of Erdos base as the object of study. Based on depth and detailed analysis of logging data, we proposed fusion of modeling method, formula method and neural network method to estimate data of S-wave, avoiding prediction error for the mudstone owing inaccurate porosity measure for Xu-White model. By the cross pictures analysis, we make clear sensitive elastic parameters for EEI inversion and effective scale for interpretation of lithology and fluid. Based on deterministic extended elastic impedance inversion, we determine the variation and range and complete the pre-stack stochastic extended elastic impedance inversion, which accurate predict the thin reservoir of 5 m and the drilling data match rate reaches above 90%.
