摘　　要：为进一步研究阿尔巴尼亚P区块混积岩储层特征,采用张雄华对混积岩的分类方法,对P区块储层发育的混积岩岩石类型进行了划分,并利用铸体薄片、全岩分析、核磁共振及孔隙度等资料,对该区混积岩储层进行了综合分析。该区储层岩性复杂,岩石类型主要为砂岩类,岩石矿物成分包括陆源碎屑、碳酸盐及黏土矿物。储层具有低孔、低渗特征,孔渗相关性一般。碳酸盐含量和沉积相类型是该区储层物性的主控因素,压实作用对储层孔隙度影响不大。For further research of Albania P block peperite reservoir characteristics,this paper adopts Zhang Xionghua’s classification method of peperite to classify the P block peperite rock types of reservoir development.By using the casting thin sections,whole rock analysis,nuclear magnetic resonance(NMR)and porosity data,peperite reservoirs of this area are analyzed.The reservoir in this area is lithologically complex;the rock type is mainly sandstone;and the rock mineral composition includes terrigenous clasts,carbonate and clay minerals.The reservoir has the characteristics of low porosity and low permeability.Carbonate content and sedimentary facies type are the main controlling factors of reservoir physical properties in this area.Compaction has little influence on reservoir porosity.
