摘要：The distinctive terrain and physiognomy character, sedimentary environment in the geological structure complex region maybe because the seismic wave velocity to change largely in the vertical direction. In this program, first set continental zone QDN-3D in slope zone of continental shelf of Southeast Hainan Basin, aim to the phenomenon of theoretical Dix formula with the assumption that horizontal structure and constant horizontal seismic wave always leads to the obtain velocity uncertain. Then apply the constrained Dix inversion based on the exponential asymptotically bounded velocity model and the well seismic unity establish model to solve the velocity calibration technique. The structure distortion affection caused by depth variation, layer velocity varied in the vertical direction can be removed well by the twice velocity obtain technique, and the algorithm is accurately and fast. Not only the trial calculation of synthetic model but also the processing of actual data all produces a geological plausible, stable result, predicts oil and gas reservoir.
