摘要: 东辛永3地区为一多油层、中高渗透复杂断块, 内部被多级断层切割复杂化, 沙河街组为其主要含油层位。在三维地震解释基础上, 针对构造形态、成因机制不明确等问题, 根据相似理论支撑, 经过材料选取、边界设定、时间确立、受力加载, 对研究区古近纪沙河街组构造演化进行构造物理模拟。模拟结果实现了研究区基本断裂特征的恢复, 验证了地震解释结果; 初期北北东、北西向伸展、后期右旋剪切及底辟上拱多期构造能够成功模拟, 明确了其成因机制, 与整体东营凹陷伸展区域应力场及郯庐断裂带转型机制相吻合。Abstract: The Yong-3 fault block in Dongxin is a complicated reservoir with multi-layers, medium and high permeability, thin oil. The main oil-bearing layer is Shahejie Formation. According to the 3D seismic interpretation, with choosing the appropriate material, setting boundaries, determining time and loading stress, physical modeling experiments of the structural development in the Shahejie Formation, Paleogene in the study area are conducted on the basis of similarity theory for the uncertainty of structural shape and the genetic mechanism. The result makes the representation of basic fracture characteristics come true to validate the seismic interpretation. It also shows that the multi-phase structural evolution history can be divided into NNE-SSW extention, NNE-SSW and NW-SE extension, dextral-slipping and diaper. Mechanically, the tectonic evolution in the study area is controlled by intense extension and the fault depression of Dongying sag and the right-lateral strike-slip of Tanlu fault zone.
