Abstract

A method for inverting a formation wave impedance using DAS borehole seismic data, including: acquiring an initial magnitude at a time window after the initial arrival time of seismic wavefield data in a well; mapping the initial magnitude to a relative wave impedance; and correcting the relative wave impedance to obtain an inverted wave impedance. Also provided are an apparatus for inverting a formation wave impedance using DAS borehole seismic data, a device, and a computer-readable storage medium.
