摘要

中国中西部前陆冲断带地表、地下构造复杂,地震资料成像品质普遍较差。针对复杂前陆冲断带的 断层相关褶皱,提出了一种在构造复杂、地震资料品质较差地区褶皱的定量构造建模方法,即应用地震波 动方程正演、平衡地质剖面数值模拟、构造物理模拟等技术,分步骤求取构造几何学、运动学参数,建立最 终的定量化构造模型,从构造变形量、变形机制、变形时间和变形过程4 个方面揭示构造变形特征。应用 该方法对准噶尔盆地南缘独山子背斜进行定量化建模,确定独山子背斜几何学与运动学构造参数,取得 了较好的应用效果。

Abstract

Due to the complexity of surface geological condition and subsurface structure of the thrust belts of foreland basins in central and western China, the qualities of seismic data imaging are generally poor. In view of this situation, a quantitative tectonic modelingmethod was put forward. The techniques such as seismic wave forward modeling, balanced geologic section numerical simulation and structural physical simulation were applied to establish the final quantitative model. The tectonic deformation characteristics were analyzed from the aspects of the amount of deformation, deformation mechanism,deformation time and deformation process. The proposed method was applied to determine the geometry and kinematic structural parameters in Dushanzi anticline in southern margin of Junggar Basin, and good results have been achieved.
