| 摘 要： | 以宝浪油田低渗透砂砾岩储层为例，主要分析了低渗透储层相对渗透率曲线的形态及变化特征和影响相对渗透率曲线形态变化的原因。分析结果表明，低渗透砂砾岩储层的非达西渗流使油相的相对渗透率增大，使水相的相对渗透率减小。孔隙结构的非均质性，特别是粘土矿物的含量和注入水水质对相对渗透率曲线的影响都很大。

| Abstract: | The relative permeability curves of low permeable glutenite reservoirs are characterized by high irreducible water saturation,narrow region of two phase flow and low relative permeability of water.The relative permeability curve types,based on the shape of relative permeability curves of water,include normal,straight,arch,humpback and the transition type between straight and arch type.This paper discusses the affecting factors for the relative permeability curve types. The effects of heterogeneity of pore configuration,specially clay mineral content and injected water quality on the relative permeability curves,are considerable. |
