摘　　要：对研究区本溪组岩性、物性等特征研究发现石英是研究区本溪组储层的砂岩碎屑的主要成分,岩屑次之,长石极少;填隙物在研究区本溪组的含量最高值可达到34.00%,最低值仅仅为4.00%,平均值则为16.40%。胶结物在研究区本溪组的含量明显大于杂基含量。The features of Benxi formation such as lithology,physical property is investigated in this paper,the results show that quartz is the main components of the reservoir sandstone detritus in this area,cutting follows and few feldspar;filler content in this area can reach 34.00%,while the lowest only 4.00%,the average is 16.40%.The content of cement in the area is significantly more than that of impurities.

关 键 词：本溪组 砂岩 孔隙度 渗透率
