摘　　要：宝浪油田宝北区块是典型的低孔低渗油藏。在对本区流动单元判别分类的基础上,结合室内相对渗透率资料,运用相对渗透率曲线归一化的方法,建立了5类流动单元及其组合的相对渗透率曲线,并对不同流动单元及其组合的相对渗透率特征进行了定性和定量比较,确定了本区储层细分组合开采的优势组合为流动单元B与C的组合,通过水驱相关参数的计算实现了对不同流动单元水驱开发特征的定量评价及预测。Baobei block in Baolang Oilfiled is a typical low permeability and porosity reservoir.Based on the classification of flow units in the research area,this paper establishes relative permeability curves of five kinds of flow units and their assemblage,applying laboratorial relative permeability data,and then compares their relative permeability characteristics qualitatively and quantitatively.It is concluded that the assemblage of flow unit B and C is optimal when the reservoir is developed by subdividing layers.This finally achieves the goal that the quantitative evaluation and prediction of waterflood development characteristic of different flow units can be made through relevant parameter calculation in common water drive assessment.
