The invention discloses a seismic wave field reconstruction method, and provides a fitting landform based wave field reconstruction method. A digital model is established by use of acquisition of exploration data and routine processing and interpretation results of the exploration data, the model is divided into grids, epicenter wavelets are initialized at grid points equivalent to field excitation positions, a seismic wave field is reconstructed at each grid point and at each time point, wave field values are recorded at the grid points equivalent to field detector positions, a reconstructed recording is obtained, the recording is processed and interpreted, a reconstruction data profile is obtained, a comparison is made between the reconstruction data profile and an actual exploration data profile, whether the exploration data processing and interpreting results are correct or not is verified, and the method can be used for evaluating the rationality of an exploration data acquisition observation system. According to the invention, the seismic wave field reconstruction method is suitable for wave field reconstruction of the complex structure of a fluctuating landform, and is high in precision and low in boundary interference, thereby being an effective auxiliary means of petroleum exploration.
