通过对什股壕地区钻井岩心观察、描述，结合室内薄片鉴定、扫描电镜等测试分析，对什股壕地区盒1段储层的岩石学、物性及孔隙结构特征进行研究。总体上储层主要为岩屑石英砂岩及碎屑砂岩，属低孔低渗储层。储层孔隙类型以粒间孔最具储集意义，储层孔隙以小孔为主，孔喉组合关系以小孔-小喉为主。将盒1段划分为4类储层，结合储层平面分布特征，对什股壕地区盒1段进行了有利区域划分，研究区以Ⅱ-Ⅲ类储集岩为主。

Based on the drilling core observation and description in Shiguhao region, combined with the interior flakes identification,scanning electron microscope test and so on, study on the petrilogy,physical properties and pore structure characteristics of He 1 in Shiguhao aera, on the whole, the reservoirs are mainly include Cuttings of quartz sand and Detri-tal sandstone, belongs to low porosity low permeability reservoir, the most meaning of reservoir pore type is intergranular hole, reservoir porosity is dominated by small holes, combination of the pore and throat is main about holes - small throat. On the basis of the above study, divided the He 1 into 4 types of reservoir, combined with reservoir horizontal distribution feature, mark off the favourable target areas of He 1 in Shiguhao aera, the main reservoir rock is Ⅱ-Ⅲ reservoir rock. Re-search results obtained for the further exploration and development has provided the important geological basis.
