The present invention relates to a method for forming an FWI initial velocity model using an NIP tomography and, more specifically, to one of the methods of exploring for underground resources by establishing the magnitude and characteristics of unearthed resources, which is a method for forming an FWI initial velocity model using an NIP tomography using the NIP theorem. Since an initial velocity model is directly calculated from real data and inputted to an FWI, the reliably and accurately calibrated velocity model can be given. Moreover, since parameters are minimized and data are optimized at the same time, an inversed operation of calculating the calibrated velocity model against a reflection wave can be conducted swiftly and accurately even when a user is using a computer having relatively low specifications. |
