| 摘要: |
| 以Miall的储层构型分析理论为指导,综合应用岩心、测井、分析化验以及生产动态资料,对升平油田葡萄花油层葡一油组进行储层构型研究,建立研究区浅水三角洲储层构型单元层次划分体系及空间结构模式。结果表明:研究区发育3种单砂体内部构型界面,即泥岩—泥质粉砂岩岩性界面、冲刷切割界面、钙质胶结砂岩界面,作为垂向上划分四级构型单元的依据;根据单一分流河道的平面形态以及空间接触关系,可以建立浅水三角洲储层简单层状叠加模式、交错迁移叠加模式、孤立单一河道模式3种空间结构类型;单一分流河道优势连通方向以及单一分流河道空间叠置关系与注采井的空间配置影响注入剂在砂体内部的驱油效果。 |

| Abstract: |
| Using cores, logging data, analysis data and production data, the reservoir architecture of Pu-Ⅰ oil group in Putaohua Formation in Shengping Oilfield was analyzed in the framework of Miall 's theory. The hierarchy system of multilevel architectural element and the space structure model of shallow delta in the study area were proposed. The results show that three types of interfaces, namely, the mud-muddy siltstone lithological interface, the erosion interface, and the calcareous cementatious sandy interface are developed in single sandstone beds. These interfaces can be used to divide the level-4 architectural element in the vertical direction. According to single channels shapes and their mutual contact relationship, three models of space structures were identified in the shallow delta reservoirs, which are the simple layered stack model, the staggered stack model and the isolated channel model. The advanced connection directions in the single distributary channel, their spatial superimposing relationship, and the relationship between injection wells and production wells affect the distribution of reservoir oil by injectants in sandbodies. |
