Almost all of the basic geological study and petroleum geology study will involve the seismic data interpretation, and 3D surface recon-struction and visualization of anomaly bodies is an important part of seismic data interpretation. In the practical seismic data, different seismic attributes often reflect different aspects of underground situation. In order to combine different seismic attributes to reflect the characteristics of target body more fully and eliminate the uncertainty of a single seismic data, proposes a new surface reconstruction method work flow of 3D target body. This workflow includes surface reconstruction method, data filling and surface smoothing. Introduces the method of 3D geological target body extraction based on data fusion of different seismic attributes, and this method adapts the method of fuzzy logic. Introduces data filling of 3D geological target body method based on morphology and surface smoothing of 3D geological target body based on Gaussian smoothing. This new workflow is used in practical project of geological interpretation, and has some nice results. It gives surface reconstruction of 3D geological body a new research thought.
