摘　　要：海拉尔盆地深层碎屑岩储层中高含凝灰质成分,显微镜分析表明储集空间类型以碳酸盐胶结物和长石类矿物溶蚀作用形成的次生孔隙为主。对凝灰质砂岩制成的铸体薄片进行了溶蚀实验,通过偏光显微镜观察对比溶蚀前后的矿物组合和孔隙变化,研究凝灰质砂岩溶蚀作用机理,为优质储层预测提供科学依据。High deep clastic reservoir of Hailar Basin is high of tuffaceous composition,and the analysis of microscopic shows that reservoir space is based on the secondary porosity formed by dissolition of the carbonate cements and feldspar minerals.A dissolute experiment of the cast thins made by the tuffaceous sandstone,observes and compares the changes of mineral association and pore space,studys thedissolution mechanization of tuffaceous sandstone,make scientific contribution to the prediction of high quality reservoirs
