分支河流体系研究进展及应用前景展望

Based on literature research and geological analysis，the research progress，application prospect and development trend of distributive fluvial system（DFS）theory were reviewed. The results show that：（1）There are five important problems should be claimed in current DFS research，including to excavate the scientific connotation of DFS through case analysis and explore its application value；DFS is a multi-channel coexisting depositional system which cannot be thought as a new pattern of channel；channels network and channels transition，as well as their evolution，are important issues in DFS study；it is urgent to build and to perfect the depositional model；predictable reservoir modelling is the way to realize the basin-scale reservoir prediction.（2）DFS are prospected to be widely developed in petroliferous basins and the researches are of great theoretical significance and application value for promoting the theoretical sedimentary innovation and oil and gas resources exploration.（3）The current study should be focused on DFS sedimentary database construction，DFS facies identification model construction，the research of quantitative DFS channel network prediction and their evolution and hierarchical DFS reservoir geological model integration. Future trend in DFS research should combine sedimentology with geomorphology，geography and Earth Information Science and technology，with the help of big data and intelligent technology，to realize quantitative depositional system prediction and reservoir characterization.
