摘　　要：低渗储层油藏开发难度大,含水率变化较难掌控。选取低渗区块岩心进行驱替,绘制了注水倍数与含水率变化关系曲线,发现了含水率变化的3个阶段。It＇s difficult to develop low permeability reservior and control water content. The core of low permeability area was chose and drove to draw the correlation curve of PV and water content. As a result, three changing steps of water content were found.

关 键 词：含水率 低渗 驱替
