摘　　要：通过文献调研和地质分析,系统总结了分支河流体系(DFS)理论的研究进展、应用前景和发展趋势。研究结果表明:(1)当前DFS理论研究的五大重点分别是通过实例分析挖掘其科学内涵,探讨应用价值,解决概念争论;明确DFS是一个多种河道共生的沉积体系,不能理解为一种新的河道类型;河道网络和河型转换是DFS研究中的重要问题;建立和完善DFS的沉积模式;建立DFS储层预测模型。(2)开展DFS研究对促进陆相盆地沉积储层学科的理论创新和挖掘陆相盆地油气资源潜力具有重要理论意义和广阔的应用前景。(3)当前DFS研究主攻方向是建立沉积储层数据库,构建沉积模式和识别标志,形成河网体系和河型演变定量预测模型,实现不同建模方法的融合归一;未来DFS研究应当将沉积学与地貌学、地理学、现代地球信息科学技术相结合,应用大数据和智能化技术,实现对沉积体系的定量表征和储层定量预测。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.
