Abstract:Yingxiongling area of Qaidam Basin has a strong wave impedance interface,which serves as the earthquake model inversion symbol layer to calculate low and high frequency static correction components.The method makes full use of the depth information,refraction information and reflection information of the interface of shallow strong wave impedance,and takes into account the low and high frequency.Large scale application of this method in Yingxiongling area improved SNR of seismic section and complex structure imaging precision,which indicates that the static correction is an effective method to solve extremely low SNR complex static correction of Yingxiongling area.
