Abstract：Since the three-dimension and three-component (3D3C) VSP data contain [KG(0.06mm]not only exact depth information but also rich lithologic information of strata, so it has incomparable advantages over surface seismic data. However, because of its special observation mode, specific processing and interpretation methods are needed. We analyze the characteristics of a deviated-well 3D3C VSP data, and propose a few methods for its data processing and interpretation, including sorting, velocity analysis, normal moveout correction, horizon calibration, horizon correlation and prestack inversion. The processing and interpretation results of the deviated-well 3D3C VSP have been obtained.
