Abstract: 3D seismic survey used to be applied in traditional two dimensional interpretations in which principal seismic line is often paid attention to from part to whole train of thought, which some adjacent or connected stratigraphic characteristics on the line direction would be omitted, leading to incomplete interpretation result. By utilizing 3D visualized technique for 3D seismic interpretation in Junggar basin, that is, 3D interactive interpretation are simultaneously made for 3D seismic data volume in principal line, branch line and time directions, it is favorable to improving the accuracy of seismic structural interpretation and recognizing distribution of lithosome. Three cases show that this visualized technique provides a new explanation for 3D seismic detailed interpretation from the view point of "body".
