Abstract
The present disclosure disclose a method, an apparatus and a system for eliminating a frequency dispersion effect, wherein the method comprises: testing a core sample to obtain logging band velocities and seismic band velocities under different pressures; fitting a relationship between a stratum pressure and the logging band velocity using the logging band velocities under different pressures, and fitting a relationship between the stratum pressure and the seismic band velocity using the seismic band velocities under different pressures; and eliminating a frequency dispersion effect in a target area using the relationship between the stratum pressure and the logging band velocity and the relationship between the stratum pressure and the seismic band velocity.
