Abstract

The Gulongnan strike-slip fracture zone consists of multi-phase active faults, which play a crucial role in the transportation of hydrocarbons generated from depressions to the slope area, and is of high research value. However, the main controlling factors of reservoir formation in the context of the development of strike- slip fracture are still unclear, and the success rate of drilling wells is low, so there is an urgent need to carry out the research work on the formation process of strike-slip fracture zones and the mechanism of genesis. Based on the principle of similarity, this paper investigates the tectonic style and evolution law of extension and extrusion under the control of strike-slip faults in the study area through tectonophysical simulation experiments, in order to reproduce the dynamical evolution process, and achieves a high degree of agreement with the actual geological situation. The experimental results show that at the end of the depositional stage of the Qingshankou Formation in the study area, a weak east-west extrusion formed the dorsal tectonics, and then a strong east-west stretching formed the strike-slip fault zone, and the tectonic pattern of the study area was controlled by the two main faults formed in the early stage of the extrusion.
