- Distributary plain facies sands body: 1).Meandering sands micro-facies, which represents large low sinuosity meandering disposition, and the channel sands is very large. 2). 一是分流平原相砂体:1、曲流河砂体微相,代表大型低弯度的曲流河沉积,河道砂体规模很大;
- then that of the subaqueous distributary channel sand bodies,diaras and river mouth bars is secondary;that of river mouth sand bars of deltaic front subfacies is the last. 三角洲平原亚相的辫状河道砂体物性最好,水下分流河道砂体、心滩砂体次之,三角洲前缘亚相的河口坝砂体最差。
- on delta plain, the acceptable space-sedimentary supply ratio (A/S) was the key factor of controlling the superposition and migration of distributary channel sand bodies; 三角洲平原上可容纳空间与沉积物供给量比值(A/S)是控制分流河道砂体叠加、迁移的关键;
