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。
Using the method of coherent data analysis and the visualization research methods, the trend and spatial distribution of the strike-slip system of Tazhong Ⅰ slope break are explained and explained in detail, and the fracture systems are classified and combined to determine the occurrence of faults Period. The results show that the fracture system of Tazhong I slope break can be divided into three stages according to the size and formation period. The first-order fault was formed in the Caledonian, the second fault in the Early Hercynian, and the third-order fault in the Late Hercynian. The fractures at all levels have different degrees of influence on the Ordovician reservoirs. Due to the succession of the fault activity, the reconstruction of the early carbonate reservoirs by the fault systems in this area is continuously superimposed.
