The present disclosure provides a method and system for stabilizing a Poynting vector of a seismic wavefield. The method includes: adjusting an amplitude of a time derivative of the seismic wavefield, and computing a Poynting vector of the adjusted time derivative of the seismic wavefield to obtain a first Poynting vector, where a difference between the amplitude of the first Poynting vector and the amplitude of a second Poynting vector is within a set range, and the second Poynting vector belongs to the seismic wavefield; and conducting operation on the second Poynting vector and the first Poynting vector to obtain a final Poynting vector of the seismic wavefield. The present disclosure addresses instability of Poynting vectors computation.
