本文以鄂尔多斯盆地华庆地区长63储层为研究对象,运用岩石薄片、铸体薄片、扫描电镜等进行观察,并结合毛细管压力法,对岩石学特征、孔隙类型、孔渗特征等进行了研究。结果表明,长63油层储层岩石以岩屑长石砂岩和长石砂岩为主;孔隙类型以粒间孔和长石溶孔为主;储层孔渗特征表现为低孔、低渗。
In this paper, the Chang 63 reservoir of Huaqing area in the Ordos Basin is taken as the research object, and the lithology, pore types and pore infiltration characteristics are studied by using the thin slices of rock, the thin cast films and the scanning electron microscopy. . The results show that the reservoirs of Chang 63 reservoir are mainly feldspar feldspathic sandstones and feldspar sandstones. The pore types are mainly intergranular pores and feldspar dissolved pores. The porosity and permeability characteristics of the reservoirs are characterized by low porosity and low permeability.
