distal-bar sand的意思|示意

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。

The main sedimentary microfacies comprise distributary channel, mouth bar, distal bar, blanket sand, natural levee and crevasse splay.

主要沉积微相为水下分流河道、河口坝、远砂坝、席状砂、天然堤、决口扇等。

Relationship between sedimentary facies and hydrocarbon distribution shows that most favorable oil and gas accumulation zones occur in the mouth bar, distal bar and sand sheet.

该区沉积相与油气分布关系分析表明，河口坝、远砂坝和席状砂微相是最有利的油气聚集带。
