摘　　要：通过岩石薄片、压汞等方法,对蟠龙油田王庄区长2致密储层特征进行研究,表明该储层岩石类型主要以长石砂岩为主,少量岩屑砂岩。储层孔隙类型为粒间孔隙和溶蚀孔隙.孔隙结构划分为大孔中-细喉型、大孔微细喉型和中孔微喉型三种类型。蟠龙油田王庄区长2储层属低渗储层。The characteristics of Chang 2 tight reservoir in Wangzhuang district of Panlong oilfield was studied by means of thinsection and mercury injection. The results show that the reservoir rock type is mainly feldspar sandstone and a small amount of lithicsandstone. Reservoir pore types are intergranular pore and dissolution pore, and pore structure can be divided into three types:macropore meso-fine throat, macropore micro-throat and meso-pore micro-throat. Chang 2 reservoir in Wangzhuang area of Panlongoilfield belongs to low permeability reservoir.
