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.
