通过岩心观察、薄片鉴定、特性分析及扫描电镜观察等，对王庄地区沙四段砂砾岩储层的主要岩石类型、成岩作用、储集空间类型及物性特征等进行了研究。根据储层物性的差异，把该区储层分为4 类，其中Ⅰ—Ⅲ类储层分布相带为该区的勘探潜力区。

Based on core observation, thin section analysis, property analysis and scanning electronic microscope, the rock type, diagenesis, reservoir spaces, physical property of the sandy conglomerate reservoir of the forth member of Shahejie Formation in wangzhuang area are studied. Accorded to the difference of the physical properties, the reservoir in this area can be divided into four types, among which type Ⅰ,Ⅱand Ⅲ reservoir facies belts are the favorable exploration area.
