鄂尔多斯盆地靖边油田曹崾岘区延9油藏富集规律
|
摘要
在对油水分布特征及油藏类型研究的基础上,采用成藏地质条件与油藏分布叠合分析的方法,对靖边油田曹崾岘区延9油藏富集规律进行了研究.结果表明,延9油藏纵向上主要分布在延92层,具有明显的边水和底水,其油藏类型以构造油藏、构造-岩性复合油藏为主.延9油藏分布和富集主要受控于曲流河边滩砂体分布和规模、储层顶面构造高点分布位置、直接盖层厚度和展布特征.三者有效配置共同控制了延9油藏富集层位和地区,东部地区砂体厚度大于10 m的构造高点石油最为富集.
The enrichment of Y-9 reservoir in Caoyaoxian area of Jingbian Oilfield is studied by the overlaying analysis of geological condition and reservoir distribution based on the discussion of oil-water distribution characteristics and reservoir types. The results show that the Y-9 reservoir is chiefly distributed in the Y-92 layer vertically,with obvious edge and bottom water,dominated by structural and structural-lithologic composite reservoirs in terms of types. The enriched horizons and areas are controlled by the effective combination of distribution and scale of meandering stream sand body,culmination position of reservoir top,and thickness and distribution of direct caprock as well. In the eastern region,oil is the most abundant at the structural culmination where sand body is more than 10 m thick.
