摘　　要：结合刘庄地区取心井的岩心观察描述、岩心分析化验等资料,从储层岩石学、物性及孔隙类型等多方面入手,对沙一段储层物性特征及其影响因素进行了认真分析和深入研究,指出沙一段储层岩性是以粉—细粒长石石英砂岩和长石岩屑质石英砂岩为主,成分成熟度和结构成熟度较高,形成中低孔、中高渗储层,且储集空间为孔隙型,储集空间类型主要有剩余粒间孔隙、方解石溶孔、岩屑溶孔及长石溶孔.工区沙一段储层物性特征是由沉积相带、储集岩成分及粒度、填隙物成分和含量及成岩作用等因素共同决定的.According to the data of core observation,core analysis test,etc.,the characteristics of the reservoir,such as reservoir petrology,physical properties and pore types,etc.,and their influencing factors are analysed.It is pointed out that,the reservoir mainly consists of silt--fine feldspar-quartz sandstone and feldspar lithic quartzite sandstone,and they have high compositional maturity and textural maturity.The reservoir has medium-low porosity,medium-high permeability.It is porous reservoir,and the types of the reservoir space mainly includes remained intergranular pore,the calcite solution pore,the cutting solution pore and feldspar solution pore.The properties of the reservoir are determined by the common effect of sedimentary facies,the composition and grain size of reservoir rock,the composition and grain content of interstitial matter and diageneses.
