A method of 3D finite-difference migration of the field of refracted waves is proposed, which takes into account their penetration into refracting strata. Theoretical grounds and special features of the method of finite-difference deep migration of the field of refracted waves have been presented in the paper. Effectiveness and facilities of application of proposed method of 3D finite- difference migration of the field of refracted waves have been demonstrated on the model example.

Key words: 3D, finite-difference migration, refracted penetrating waves, eikonal equation.
