摘要
根据岩心、薄片、物性、高压压汞等资料对曹崾岘区延9储层特征进行了研究。延9储层以中-粗粒岩屑长石砂岩和长石砂岩为主,碎屑含量高;填系物成分主要为高岭石。储层物性好,面孔率大,孔隙结构简单,综合评价延9储层以Ⅰ类为主,该研究对曹崾岘延9油藏后续开发具有一定指导意义。
The characteristics of Yan9reservoir in Caoyaoxian area are investigated by use of the cores,thin sections andphysical properties,high pressure mercury.Yan9reservoir is mainly composed of coarse to medium grained lithic feldspathicsandstone with high detrital content,and the main composition of filler is kaolinite.The reservoir features good physical properties,large face ratio and simple pore structure,and the comprehensive evaluation indicates that the reservoir is dominated by type I.Thisresearch offers guidance for the further development of the reservoir.
