distributary channel sand

Sand lens reservoirs and lithologic reservoirs which the underwater distributary channel sand cut by fault develop in syncline area.

向斜区主要发育水下分流河道被断层截切的断层岩性油藏和砂岩透镜体油藏。

Distributary channel sand bodies of above FII2 small layer is best reservoirs, which is key evidence for exploration and development in the future.

FII 2小层以上的分流河道砂体是研究区主要的油气聚集体，为今后勘探和开发提供了重要依据。

The channel of meandering river, the distributary channel of delta front , distributary mouth bar , distal bar and the beach bar are the main sand body types.

其中曲流河河道，三角洲前缘水下分流河道、分流河口砂坝、远砂坝以及滩坝是主要的砂体成因类型。
