摘　　要：通过对过吐谷鲁背斜地震剖面的构造解释,分析了吐谷鲁背斜深部构造的组合样式:深部断层在吐谷鲁处形成一构造三角带,导致对应的复合叠加褶皱的出现。在构造解释的基础上,利用地震主剖面与联络剖面的栅状图和地震主剖面的排列图。Through structural analysis of the seismic sections of Tugulu anticline, the structural styles in the depth of Tugulu anticline were studied in this paper. The deep fault that propagated towards the foreland resulted in the formation of a triangle zone at Tugulu and the composite stacking folds. Based on results of structural analysis and interpretation of 2D seismic data, and by using the grid map consisting of inlines and crosslines for seismic data and the rearranged map made up of inlines, the landscape orientation and distribution as well as the imitated 3D structural model of the Tugulu anticline were shown in this paper.
