Using the phase shift of reflection coefficient of SH seismic wave at the interface of strata, we derived the lateral shift and group time delay of total reflected SV-wave, given formulae of normal moveout of lateral shift, discussed the influence of lateral shift on normal moveout of SV-wave, and drawn the curves of normal moveout of lateral shift and the error of normal moveout caused by lateral shift with respect to the angle of incidence.The results show that for glancing wave or angle of incidence being near the critical angle, A large error can be caused by lateral shift; The error correction of lateral shift should be done before seismic data processing.
