Method, apparatus, and system for eliminating frequency dispersion effect

An apparatus for eliminating a frequency dispersion effect, comprising a memory, a processor, and a computer program stored in the memory and runnable in the processor;

• when executing the computer program, the processor performs the operations of:
• 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.
