| 摘 要： | 通过对鄂尔多斯盆华庆地区延长组长63储层岩心和铸体薄片等进行观察,结合测井数据分析,对其岩石学特征、孔隙类型、储层孔渗特征等进行了研究。结果表明,长63油层组储层岩石以长石砂岩为主;孔隙类型主要为次生孔隙的粒间溶孔和粒内溶孔;储层孔渗特征表现为中低孔特低渗;中-细粒长石砂岩物性相对较好;粘土矿物和千枚岩岩屑含量增高,碎屑组分稳定成分降低,基质含量增高,孔隙不发育,导致物性变差;各成岩作用中,溶解作用对储层物性起建设性作用,压实作用和碳酸盐胶结作用对储层物性起破坏性作用。

| Abstract: | Parameter quantitative research of the reservoir properties and research on the plane and vertical variation of the reservoir are very important for the study of anisotropy and comprehensive evaluation.Drilling core,thin section and cast thin section observations and study on scanning electron microscope in combination with actual data and well logging data analysis show that the reservoirs consists mainly for arkose and lithic arkose with intragranular dissolved pore and intercrystalline pore.The high-valu... |
