Abstract:

The "Source-to-Sink" system has been the focus of sedimentology research in recent years.In this paper,new research advances of "Source-to-Sink" at home and abroad are systematically reviewed,research methods and multi-methods integrated analysis technologies of the "Source-to-Sink" system are summarized and research trends are predicted.The "Source-to-Sink" system in continental margin basins focuses on the drivers of sedimentary event and transportation process,while in complex continental rift basins,principle of temporal-spatial coupled "Source-to-Sink" sandstone control and corresponding sandstone distribution models have been innovatively established.The "Source-to-Sink" research also focuses on application of multiple methods in sediment tracing to reveal paleo-provenance and reconstruct paleo-drainage.For the "Source-to-Sink" system in a provenance of continental rift basins,detailed analysis of sequence stratigraphy in potential eroded zone recovers the initial features of disappeared provenance in geological history.Quantitative characterization of the elements in the "Source-to-Sink" system and quantitative reservoir prediction has been under study,and establishment of quantitative relationship from source to sink is the final purpose.Sedimentary process simulation under the quantitative constraint provides significant support to reservoir prediction in sparse wells conditions.The research trends of "Source-to-Sink" include the following aspects:to improve provenance system research,to experiment on quantitative reservoir prediction,to combine multiple subjects and methods,to emphasize on process and mechanism analysis,and to form industrial application standard.

Key words: Source-to-Sink, provenance tracing, principle of spatial-temporal coupled sandstone control, regional provenance, quantification, sedimentary simulation, continental margin basin, continental rift basin
