Abstract:The strike slip faults are widely distributed in Bohai sea area and they play an important role in the formation and evolution of the sedimentary basin and the Source-to-Sink system.According to the principles of Source-to-Sink system analysis,this paper focuses on the study of control of the strike slip fault over the Source-to-Sink system of the Paleogene in Bohai on the basis of a large number of drilling data and seismic data analysis.It is found that the transpression of the strike slip faults controls the formation of local provenance system.and the transtension of the strike slip faults controls the formation of eroded ravines and valleys.The horizontal movement of the strike-slip fault controls the lateral migration of Source-to-Sink system.The Source-to-Sink system in the strike slip fault zone is more complex than that of the simple extension fault zone.There are four kinds of common Source-to-Sink system of strike slip faults in Paleogene in Bohai including S type strike slip fault source sink system mode,en echelon type strike slip fault source sink system mode,brush strike slip fault source sink system mode,and conjugate strike slip fault source sink system mode.The study on the characteristics of Source-to-Sink system and its sand control pattern of strike slip fault zone is very important for reservoir prediction in petroliferous basin.
