Determination of Surface Seismic Data Frequency by Micro Logging and Vertical Seismic Profile (VSP) Data
Because zero-or nonzero-offset VSP data has ability to reduce influence of low velocity layer, shorten propagating path of seismic wave and lessen disturb of surface noise, it can remedy some defects of surface data. After influence of disturb from surface is eliminated, frequency and amplitude of seismic wave which transmitted exploration target layer in different depth can be determined by VSP data. By comprehensive utilization of logging, VSP data and surface seismic data, we can get the highest frequency of seismic acquisition. So it can guide the test of seismic acquisition and evaluation test data.
