准噶尔盆地褶皱基底三维构造模型的建立

Development of 3D Structural Model for Folded Basement in Junggar Basin

简要介绍了准噶尔盆地基底性质的研究进展。在现有各类地形、构造和深部勘探数据的基础上,使用地理信息系统软件和GOCAD三维建模软件,对准噶尔盆地各构造层数据中存在的穿层现象进行校正,建立各构造层的层序-构造模型。根据准噶尔盆地褶皱基底与盖层的接触关系,进一步建立了准噶尔盆地褶皱基底的初始模型,并利用深部地球物理勘探资料对初始模型进行约束和校正,建立了准噶尔盆地现今褶皱基底构造模型,为准噶尔盆地盖层和基底构造的研究提供了重要的参考资料。

The studied progress on basement property of Jungear basin is briefly introduced. Based on available information about various terrains, structures and deep geophysical explorations, with geographic information software （GIS） and GOCAD 3D modeling software, the translayer phenomena existed in geo-structural data in Junggar basin are corrected, and the sequence-structure model is developed. Moreover, according to the contact relationship between the folded basement and the cap rocks in the basin, the primary model for the folded basement is given, and constrained and corrected using the deep geophysical prospecting data, followed by providing a recent and valuable folded basement model for study of the cap rocks and basement structures in Junggar basin.
