【Abstract】 Multiwave AVO/AVA double inversion method was analyzed in the paper. The combined seismic AVO/AVA analysis of longitudinal wave and converted wave with seismic inversion, the simulated annealing global optimization technology was used to estimate horizon elasticity constants by the amplitude and time of matching longitudinal wave and inverted wave. The elasticity constants with high precision and good actual results have been obtained in Ken 71 Area by using the double inversion method, which could provide a new basis for the lithology prediction and fluid detection in the studied area.更多还原
