摘　　要：水驱前后储层物性参数将发生变化,这些变化将导致储层渗流单元模型的变化。以此为基础可以建立水驱前后储层渗流单元模型并研究其变化规律。储层渗流单元的建立采用层次研究,首先确定连通体和渗流屏障分布;然后在连通体内确立主控参数,划分渗流差异界面,建立水驱前后储层渗流单元模型,比较水驱前后模型的变化规律。研究结果对油田开发后期制定合理的控水稳油措施具有指导意义。Petrophysical parameters of the reservoir bed before and after water flooding will change,which will result in seepage unit model change.Models of reservoir seepage unit before and after water flooding can be established and their changing regularity can be studied according to these changes.This models are established through hierarchical research and connected body and seepage barrier distribution are determined firstly,and then main control parameters are established in the connected body,seepage difference interfaces are divided,models of reservoir seepage unit before and after water flooding are established and their changing regularity is compared.The research results have very important significance for preparing rational measures of water control and oil stabilization at late stage of oil field development.
