Seismic Record Simulation of the Coalbed In HTI Media

摘要

This paper uses the finite element simulation system of the anisotropic elastic wave to simulate the two component wave field characteristics of the HTI medium in the coal-seam with fractures.The simulation results of the single shot record indicate that when the coal-seam contains fracture.The wave field characteristics under different fracture parameters are observed through the single shot record.The influences can be found mainly in the energy and amplitude vers offset characteristics.The characteristics of x component and z component are different.This may provide some experimental references to fracture detection using the PS-wave.
