The Application of 3D tectonic restoration and dynamic strain in Strike-slip tectonic belt, A case study from Bohai Bay Basin, NE China

摘要

Rock strata usually deform in 3D space in the process of tectonic evolution. With the development of computer technology and 3D visualization technology in recent years, 3D tectonic restoration technology has been widely used in petroleum basin research and exploration. The process of stratigraphic sedimentation is usually sedimentation-compaction-fold-fault. The recovery of 3D paleotectonic is actually the inverse process of stratum sedimentary deformation. Therefore, the process of tectonic restoration can be divided into three steps: de-fault, de-fold and de-compaction. Finally, the depositional state of the target layer without deformation is obtained.
