Vertical seismic profiling (VSP) technology plays an important role in oil and gas exploration. It can obtain data in the well with higher resolution than conventional surface seismic imaging methods, and effectively identify small faults along the well, thereby improving the description accuracy of the reservoir. Gaussian beam migration (GBM) has the ability to calculate the multi-arrival travel time, which has the advantages of both high efficiency and high imaging accuracy. In this paper, the observation system and the local plane wave decomposition step will be adjusted to expand the prestack GBM into a VSP imaging method. A layer model and a complex model will be employed to verify the imaging ability of VSP GBM. The correctness of VSP GBM will be proved by practical data test through comparing the results of VSP GBM with Kirchhoff migration in surface seismic.
