Abstract:
At present, mainly kinematic records are processed by wave refraction method [2, 3]. Usually, refracting boundaries and velocities (boundary, stratal, and average) are shown on the seismic profiles. Dynamic peculiarities of the waves are used to a lesser extent and are applied mainly to determine the nature of waves and their division at the stage of kinematic parameter readout. The correlation of wave amplitudes with the refraction coefficient (head wave refraction) is not taken into account. Hence, sharp changes in acoustic properties at the boundary are also not taken into account, unlike the wave reflection method, which makes wide use of the above changes. Various methods exist for using the kinematic and dynamic properties for constructing specific refracting boundaries including those based on the migration of records. However, these methods solve only particular problems of the processing of refraction survey data [1, 3, 4, 5]. We propose performing the entire processing of refraction survey data on the basis of migration of records.
