Traveltime parameters in tilted transversely isotropic media

摘要: ABSTRACTTraveltime parameters define the coefficients of Taylor series for traveltime or squared as a function offset. These provide an efficient tool analyzing effect medium short- and long-offset reflection moveouts. We derive exact equations one-way two-way in homogeneous transversely isotropic with tilted symmetry axis (TTI). It is shown that most TTI differ from parameters, we observe strong dependence all on tilt. The are extended to vertically heterogeneous medium, weak-anisotropy weak-anellipticity approximations considered. also apply approximate invert into model different acquisition setups. Using approximation, our tests show ...
