| Abstract: |
| The analysis of fine structure explanation of seismic data and regional geology shows that it is controlled by Indosinian, Yanshanian and Himalayan movements and three types of faults, including negative structural inversion, strike-slip extension and structural adjustion, develop in Chengdao Buried Hill. Both the negative inversion faults near the Paleogene sag and the strike-slip extensional faults communicated with unconformities play an important role in vertical hydrocarbon migration, while the structural adjustion faults act as lateral barrier for hydrocarbon accumulation. It is suggested that the fault system controls the hydrocarbon accumulation in many oil-rich zones. |
