赵石窑河道砂体成分成熟度和结构成熟度均较低，岩屑和长石含量较高，泥质、硅质、铁质和碳酸盐为主要填隙物，经历了同生、埋藏和表生３个成岩阶段。粒度是造成储层岩性相孔渗性差异的主要原因，可识别出８种孔隙类型和大孔中喉、大孔细喉、中孔细喉和微孔微隙型Ⅳ种孔隙结构，孔隙结构及分布与粒度和填隙物密切相关。曲流点坝相中下部孔渗性最好，底部次之，顶部及边缘最差。
The maturity and structural maturity of the Zhao Shiyao channel sandbody are relatively low with high content of cuttings and feldspars, with the major interstitial material being shale, siliceous, iron and carbonate, And epigenetic 3 diagenetic stages. The grain size is the main reason for the difference in porosity and permeability of lithologic facies. It can identify eight kinds of pore types and four types of pore structures of macropore throat, macropore throat, mesopore throat and micropore micro-gap, Structure and distribution are closely related to particle size and interstitial material. The mean pore permeability in the middle and lower part of meandering point dam phase is the best, followed by the bottom, the worst at the top and the edge.
