摘　　要：本文分析了多波AVO/AVA双反演方法。将纵波、转换波地震AVO/AVA分析与地震反演相结合,采用模拟退火全局优化技术,通过匹配纵波和转换波地震数据的振幅和时间信息估算地层弹性参数。利用该反演方法在垦71地区实际应用中得到了高精度的弹性参数,实际效果显著,为研究区岩性预测和流体检测提供了新的依据。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.
