摘　　要：通过叠前地震资料反演,获得反映岩性和流体成分的弹性参数(P波阻抗、S波阻抗、密度)模型,进行岩性和流体的预测,砂体展布特征、砂体厚度及储层物性预测,在永安地区隐蔽圈闭砂体预测中获得了较好的效果,反演剖面层次清楚,目的层属性特征清晰,预测结果与钻探结果基本吻合。By inverting the pre-stack seismic data,the elastic parameters model （e.g.resistance of P wave,resistance of S wave and density） reflecting the components of lithology and fluid will be obtained to forecast the lithology and fluid properties,and further forecast the distribution and thickness of sand body,and the properties of reservoir.The technique has obtained good results in the forecast of subtle trap sand body in Yong＇an area.The inversion profile has clear level,with clear attribute feature of target zone,and corresponding with the actual drilling result.
