摘要：
It is important to know the shape and distribution of sandstone bodies in the subsurface when formation and migration of a dune model are determined. The information plays a significant role in identification of the continental oil and gas accumulation. In this study,the combination of ground penetrating radar( GPR)and electrical resistivity tomography method( ERT) is used in mapping the distribution of sandstone bodies in Yanchang Formation. Six GPR profiles and seven ERT profiles are used to analysis. GPR data show clear reflections from the top interface of sandstones. ERT data show a continuous high resistivity anomaly corresponding to the sandstone body. Combined the reconstructed 3D images by GPR and ERT,the spatial distribution of sandstone bodies is described.
