摘　　要：新疆油田是我国油气勘探的重要地区之一。利用岩石薄片、铸体薄片及压汞分析等多项资料对储集层进行了分析,研究表明J1b52层主要岩石类型有灰色砾岩、砂砾岩、含砂质砾岩等,各类岩石均为颗粒支撑,胶结致密,压嵌胶结为主,岩石中砾石颗粒主要为凝灰岩、花岗岩及安山岩岩块等岩浆岩碎屑,也有少量变质岩碎屑。储层以次生孔隙发育为主,孔隙发育程度及连通性均较差,孔隙结构不好,以低孔低渗的差储集层为主。Xinjiang Oilfield is one of the most important districts for oil and gas exploration and development in China. Kinds of experiments methods including rock slice, casting slice and mercury penetration are used to research on the reservoirs, the results indicate that main rock types of J1b5^2 are grey conglomerate, glutenite, sandy conglomerate with structures of grain supported and compact cementation, especially press-fit cementation. Conglomerate grains in these rocks are mainly magmatic clastics of volcanic tuff, granite, and andesite, and also few metamorphic rock debris. Secondary pore system with lower porosity and permeability developed in the reservoirs here and the pore fabric is also not very good.
