Abstract: Junggar basin has been explored for a long time. Using a mass of 2D and 3D seismic horizons-interpreted data from the whole basin to make a once mapping is hard to ensure the accuracy of mapping, due to the tremendous quantity of seismic data and the various difficulties of technology. This paper introduces a new method for it. That is, the 2D and 3D seismic horizons and faults interpretation data are output in batches and gridded separately, and then make a merger of grids followed by gridding, thus realizing the fast and effective output of massive data and high- accuracy mapping for the whole basin. This technology not only embodies the structural tendency of 2D work area, but also represents the structural details of 3D work area, being a successful probe in once mapping with basin-scale 2D and 3D massive seismic data.

Key words: Junggar basin, seismic data, data output, multiple merged grid, high accuracy, structural map
