利用相干数据体分析方法,结合可视化研究手段,对塔中Ⅰ号坡折带断裂系统的走向、空间展布特征进行了精细对比解释,并对断裂系统进行了分类及组合,厘定了断裂的发生期次.结果表明:塔中Ⅰ号坡折带断裂系统根据规模大小及形成期次可划分三级.一级断裂形成于加里东期,早海西期形成的断裂为二级断裂,晚海西期形成的断裂为三级断裂.各级断裂对奥陶系的储层都有不同程度的影响,由于断裂活动的继承性,该区断裂系统对早期形成的碳酸盐岩储层的改造作用是不断叠加的.%By using coherent body analysis and visualization, the strike direction and spatial distribution characteristics of the fault systems of Tazhong No. 1 slope break belt are finely correlated and interpreted; the fault systems are classified and grouped; and the occurrence stages of the faults are clarified. The results show that the fault systems of Tazhong No. 1 slope break belt can be divided into three levels according to fault scales and occurrence stages. Level 1 faults were formed in the Caledonian period; level 2 faults were formed in the early Hercynian; and level 3 faults were formed in the late Hercynian. The faults in different levels have varying influence on Ordovician reservoirs and the transformation action of the early - formed carbonate reservoirs resulted from those faults was continuously superimposed due to the inheritance of faults.
