摘要
曹崾岘地区位于陕北靖边地区,属于鄂尔多斯盆地伊陕斜坡中部。在大量的岩心铸体薄片、X衍射、扫描电镜及物性资料统计分析的基础上,总结研究了陕北靖边油田曹崾岘地区延安组延9油藏储层特征及物性,得出结论:该地区岩石成分主要以长石质石英砂岩、长石砂岩为主。孔隙类型以原生粒间孔为主,储层物性上,延9油藏分为两个小层,延91孔、渗好于延92。
Caoyaoxian area is located at Jingbian county,north of shaanxi province in Ordos basin.Reservoirs characteristics and physical properties of the Yan 9 reservoir in Caoyaoxian area were studied by many cast thin slices,X-diffraction,scanning electron microscope and statistical analysis of physical properties.The results show that： components of rocks in the area are feldspathic quartzine and arkose zandstone.The type of pores is intergranular pores.Based on reservoir physical properties,Yan 9 is divided into two junior layers,and porosity and permeability of Yan 91are better than those of Yan 92.
