【Abstract】 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.更多还原
