Through accurate description and dissection of deltaicfront outcrops, 11 petrographic facies types are established.
通过对三角洲前缘露头的精细描述和解剖 ，建立了研究区 1 1种岩石相类型。

Based on the principle of hierarchical analysis, the deltaicfront is divided into 5 hierarchies, for which the rock types, its distributional characteristic for each interface are analyzed.
依据层次分析法原理，将三角洲前缘共划分出5个层次，分析了各级界面的岩石类型、分布特征及物性特征。

The favourable reservoir sandstones in these gas pools may broadly be assigned to the deltaicfront channel mouth bar, deltaic plain distributary channel bar and fluvial channel bar microfacies.
