摘　　要：依据Garmsar区块Te-1井岩心资料及露头资料,结合测井资料、物性测试资料及前人研究的成果,对Garmsar区块Qom组E段储层的岩石学特征、储集空间类型、物性特征进行研究,结果表明:Qom组E段储层的主要岩石类型为灰色浅滩相泥灰岩、生物屑灰岩、泥晶生物屑灰岩、生物屑泥晶灰岩、泥岩及具溶孔的生物屑含云灰岩。孔隙类型以粒内溶孔、粒间溶孔、铸模孔和生物体腔孔为主。物性总体表现出低孔隙度、特低渗透率特征,沉积环境和成岩作用是控制储层发育的主要因素,Qom组E段主要发育Ⅱ类、Ⅲ类储层。Based on outcrop observation and core analysis of Te-1 well in Garmsar block, combined some data obtained from well logging and physical-property testing, E Member Reservoir of Qom Formation is studied, involving its petrology, space type and physical property. It is illustrated that (1) this reservoir is mainly composed of grey shallow-facies marl, bioclastics limestone, micritic bioclastics limestone, bioclastics micritic limestone, mudstone and bioclastic limestone with dissolution pore; (2) pore types include mainly intragranular and intergranular dissolution pore, mould pore and organicvisceral pore; (3) it is characterized by low porosity and extra low permeability; (4) the main factors influencing reservoir development are sedimentary environment and diagenesis; and (5) II-type and III-type reservoirs are mainly developed in E Member.
