摘要
This paper used staggered-grid high-order finite-difference scheme to simulate the propagation of source wavefield and reverse time propagation of receiver wavefield to finish elastic prestack reverse time migration in combination with energy flux density vector correlation imaging condition.The results of imaging for a two-layer model and a metal mine model prove that the scheme described in this paper can image the complex structure with steep reflector and eliminate artifacts in reverse time migration for elastic wave.
