Abstract
Using the lateral ,shift and shift time of REFRACTION coefficient of SH seismic wave at the interface of strata, we derived and given formulae of normal move out of lateral shift, discussed the influence of lateral shift on normal move out of SH-wave, and drawn the curves of normal move out of lateral shift and the error of normal move out 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.
