According to the difference of the reservoir architecture model of shallow lacustrine delta, this paper comprehensively applies the core, logging data, satellite photo etc. to establish the reservoir architecture model of delta plain distributary channel and delta front underwater distributary channel based on the investigation of present meandering river shallow lacustrine delta sediment of Poyang Lake and the study of paleo reservoir architecture model of meandering river shallow lacustrine delta of Fuyu reservoir of Fuyu oil field. The results show that: Meandering river shallow lacustrine delta include meandering distributary channel(main reservoir architecture is lateral accretion bodies of point bar), braided distributary channel (main reservoir architecture is vertical accretion of channel sand), straight underwaterdistributary channel( main reservoir architecture is vertical accretion of distributary sand bars). This paper concludes the distinguishing marks of the different types of distributary channel and underwater distributary channel sand bars according to the sub-facies, sand body geometry, tendency and dip of interlayer, abandoned channel, crevasse splay, granularity analysis, laying the foundation of studying the reservoir architecture and geological modeling.
