摘　　要：通过大量研究表明:广安地区须六段储层岩石学特征以中～粗粒岩屑砂岩及长石岩屑砂岩为主。须六段储层经历了强烈的压实——压溶作用、胶结作用和溶蚀作用。主要的储集类型以孔隙型为主,亦存在裂缝——孔隙型。储集空间主要为粒间溶孔和剩余原生粒间孔。储层主要是受沉积,成岩及构造作用的影响,其中沉积作用是根本,构造作用是条件,成岩作用是关键。A large number of studies show that the rock reservoir characteristics of Guang＇an area from the 6nd member of Xujiahe Formation is as following： The sandstones of reservoir were mainly middle to coarse grain lithic sandstone,feldspar lithic sandstone.The 6nd member of Xujiahe Formation experienced strong compaction and pressure solution,cementation and dissolution.The main reservoir types is pore type,there is also a fracture-pore type.Reservoir space is mainly intergranular dissolved pore and residual original intergranular pore.The reservoir is mainly affected by the deposition,diagenesis and tectonic effect,the deposition is fundamental,tectonic action is the condition,diagenesis is the key to reservoir.
