摘　　要：以往三维地震只是运用传统二维解释方法，其解释思路从局部到整体，往往只重视主测线，这样在连络测线方向的地层特征就可能会被遗漏掉，造成解释结果不完整。通过三维可视化技术在准噶尔盆地三维地震解释中的应用，即对三维地震数据体同时在主测线、连络测线以及时间方向进行三维交互解释，有利于提高地震构造的解释精度和识别岩性体的空间，通过三个实例说明了三维可视化技术从“体”出发，为三维精细解释提供了全新解释手段。D 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 visual-ized 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 accu- racy 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'.
