Description

technical field [0001] The present invention relates to the technical field of seismic exploration, in particular to numerical simulation technology in the field of seismicity, specifically a method, system, computer equipment and computer-readable storage medium for numerical simulation of seismic vector wave field based on mixed swarm intelligent algorithm. Background technique [0002] Finite difference numerical simulation technology began in the late 1960s. It has been widely used in seismic numerical simulation, migration imaging and geophysical inversion. The advantage of using the finite difference method for numerical simulation of seismic wavefields is that large-scale CPU / GPU clusters can be used to process massive data, but the disadvantage is that numerical dispersion is bound to be introduced. The occurrence of numerical dispersion is due to the use of differential operators to approximate the differential operator, which leads to errors after truncation. Ther...
