Introduction
-
The dimensions of the velocity model, shot-receiver configuration,
methods for calculation of the recorded wave field and the migration
are the same as in the papers by Bucha (2011, 2012a, 2012b, 2013a)
-
We use the Kirchhoff prestack depth migration to calculate
migrated sections in simple anisotropic homogeneous
velocity models in order to demonstrate the impact of
rotation of the tensor of elastic moduli
on migrated images.
-
The recorded wave field is generated
in models composed of
two homogeneous layers separated by a non-inclined
curved interface.
The anisotropy of the upper layer is orthorhombic
or triclinic
with the rotation of the tensor of elastic moduli.
-
We apply the Kirchhoff prestack depth
migration to
single-layer velocity models with different types of anisotropy:
orthorhombic and triclinic anisotropy with
and without
the rotation of the tensor of elastic moduli.
-
We show the errors of the migrated interface caused by
incorrect
velocity models used for migration.
