Wave field simulation of VSP record based on BISQ model in two-phase EDA medium
|
Abstract:
This paper adapts more exact finite difference method of staggered grid to carry out numerical modeling in seismic elastic frequency band.We give some sample to simulated VSP record(data).Its results confirmed that this method is feasible and valid.The study shows the amplitude of slow compressional-wave(P-wave) is directly proportional to the rate of saturation and inversely proportional to porosity.And the velocity of slow compressional-wave(P-wave) is in direct proportion to the porosity and the density of fluid.
