| 摘 要： | 以储层微观特征及孔隙结构分析为手段,对高南油田低渗储层的特征及其控制因素进行了研究.结果表明:高南东三段储层岩石类型以长石岩屑砂岩及岩屑长石砂岩为主,储层中起决定作用的孔隙类型主要为粒间溶孔及长石粒内溶孔;喉道主要为片状及弯片状,发育了大孔粗喉型、大-中孔中-细喉型、中孔细喉型、细孔细喉型、微细孔喉型等5种孔喉组合类型;高南东三段60%以上的储层属低渗储层,砂体成因类型、成岩作用及储层微观孔隙结构等是控制低渗储层形成的主要因素;多数低渗储层属于分流河口砂坝成因,压实作用是低渗储层形成的关键成岩作用,储层中喉道直径均值较低及喉道类型是决定研究区储层低渗的直接原因.

| Abstract: | The low permeability reservoir characteristics of Gaoshangpu Oilfield and its control factors were studied through microscopy and analysis of pore structure.The results show that feldspathic lithic standstone and lithic arkose are the main rock types of reservoir in Gaonan area.Intergranular and inner granular porosity of feldspar are the most important pore types in this area.The main throats types are lamellar and curved lamellar throats.Five pore-throat combination types including big pore and coarse thr... |
