© Verpakhovskaya A.O.

Since their existence seismic methods for studies of the Earth interior were based on the allocation and tracing of refracted waves. Further development of the method of refracted waves (MRW) was associated with the creation of methods for processing and interpretation of the wave fields observed on the Earth surface for solving specific problems of regional, engineering and seismic exploration. The article considers the main stages of processing methods of observed wave field based on kinematic and dynamic characteristics of refracted waves, identified current actual problems associated with further development of finite-difference refraction field migration.
