【摘要】 根据流动单元的基本理论和方法 ,对江苏油田真 12块垛一段六油组 (E2 S61 )储层进行了研究 ;用聚类分析方法 ,依据流动层段指标 (FZI)划分出一、二、三、四类流动单元 ,分析了各类流动单元的岩性及物性特征 ;并用测井资料对区块内 4 0口单井进行流动单元评价 ,从而绘制了区块流动单元分布图件 ,阐述了油组内各砂岩段流动单元及剩余油分布特点。更多还原

【Abstract】 Based on the basic theory and method about flow unit, research is made on the E 2S 6 1 formation in block Zhen 12 of Jiangsu oil field. The formation is divided into four types of flow unit using cluster analysis method. Each type of lithology and petrophysical property are analyzed. The flow units of about 40 wells are evaluated based on log data and core data, and then distribution maps of the flow unit in this block are plotted. As a result, the distribution of the flow unit and residual oil in the sandstone of E 2S 6 1 formation are illustrated.更多还原
