The quality of the acoustic waves as the basic of seismic impedance inversion is hard to be obtained because of the limits of well logging environment and geologic conditions. The velocity of sand and shale can be divided completely by use of pseudo-acoustic re-configuration based on logging curves for reference of later seismic impedance inversion.%良好的声波质量是地震波阻抗反演的基础条件。但是受测井环境和地质条件本身的限制，声波很难达到可以直接反演的效果。基于测井曲线重构的拟声波技术可以将砂泥岩的速度完全分开，为后期的波阻抗反演技术奠定基础。
