By the influence of river course, underwater distributary channel distributes alternating with interdistributary bay which forms the principal source-reservoir-seal assemblage mode.

受河道迁徙冲刷影响，水下分流河道和分流间湾相间分布，形成研究区主要生储盖组合形式。

Physical properties of the sandy conglomerate reservoirs differ greatly in different depositional environments, and the best occurs in underwater distributary channel on fan delta front.

砂砾岩储层的物性随着沉积环境的不同表现出较大的差异，且以扇三角洲前缘亚相水下分流河道微相最好。
