摘　　要：从岩石学特征、孔隙特征、喉道类型、孔喉关系4个方面对洛带气田蓬莱镇组储层特征进行了研究，并分析了其储层特征的影响因素。研究表明，研究区主要为岩屑石英砂岩，成分成熟度和结构成熟度较高，粒度以细粒为主，分选中等；以粒间溶孔、原生粒间孔为主；储层孔隙度主要集中在3％～15％，渗透率大部分大于0．2mD；储层为孔隙型储层；研究区分布面积最广的为水下分流河道沉积微相；成岩作用主要有压实作用、胶结作用和溶蚀作用。By studying reservoir petrology characteristics,porosity character,throat types and pore throat relationship of the reservoirs in Penglaizhen Formation of Luodai Gas Field in Sichuan Basin,it analyzes the reservoir characteristics and the influential factors.Studies show that the main types are lithic quartz sandstone,it has high compositional maturity and textural maturity with fine grained and medium separation,intergranular dissolved pore,primary intergranular pore. Reservoir porosity is mainly concentrated in 3% ~15%,and most of permeability is greater than 0.2mD,reservoir is pore type reservoir.It is widely distributed in an underwater distributary channel sedimentary micrafacies.The diagenesis mainly includes compaction,cementation and dissolution.
