【摘要】 以东营凹陷中、古生界构造特征为研究对象,依托高精度三维地震反射资料,通过地震反射界面确认、构造形迹精细解剖,重构了东营凹陷轴向基岩推覆褶皱带,发现了南北向走滑带,分析了剪切带的几何学特征,探讨了东营凹陷深层构造的动力成因机制。该项研究对深化东营凹陷深层勘探具有重要的地质意义。更多还原

【Abstract】 Taking the structural features of Mesozoic and Palaeozoic in Dongying sag as research target, based on high precision 3D data, confirming seismic reflectors and finely interpreting structures, a meridional strike-slip system was found, the geometric feature of the shear zone and dynamic genesis mechanism of the deep structures in Dongying sag were analyzed after axial basement nappe system was reconstructed. This is an important research in deepening the deep exploration in Dongying sag.更多还原
