Multiscale syncretized acoustic impedance inversion using poststack seismic data
地震资料波阻抗多尺度融合反演

According to optimum constrained inversion tactics,this paper applies wave equation multiscale inversion to inverse impedance of middle frequency band,and applies neural network(NN) to calibrate impedance of middle frequency band and syncretize the impedances for low,middle,high frequency band,so it can avoid the overlap of the impedances for low,middle,high frequency band and the error of inversion of low precision impedance of middle frequency band.The method has many advantages such as low dependence to initial model,high constringency speed, stable result,strong antinoise ability.
