摘　　要：在文献1的研究基础上，建立了过渡型水驱特征曲线，并导出了相应的油水两相渗流特征。通过这些理论研究，表明Wp＋C型和Lp＋C型水驱特征曲线只是过渡型水驱特征曲线参数值分别取0和1时的两种特例。而对于大多数注水开发的砂岩油田，其水驱油特征一般介于活塞式驱与非活塞式驱之间，因此应选用过渡型水驱特征曲线进行评价和预测，否则将会出现应用Wp＋C型水驱特征曲线预测的可采储量偏小，应用Lp＋C型水驱特征曲线预测的可采储量偏大，以及在高含水期Wp＋C型水驱特征曲线出现上翘和Lp＋C型水驱特征曲线出现下滑等现象。： On the basis of study of literature1， the paper established the transitional water－displacement curve and derived the corresponding oil－water percolation characteristics． From these theoretical studies， it is indicated that the Wp＋C and Lp＋C water displacement curves are the exceptional cases when the parameter values of the transitional water displacement curves are defined at 0 and 1 respectively． However， for most water－flooding sandstone oil fields，their water－drive features are generally between the piston－like displacement and non－piston－like displacement， so we should select the transitional water displacement curve to carry out evaluation and prediction， Othewise， the predicted recoverable reserves would be lower when using Wp＋C water displacement curve while higher when using the Lp＋C water displacement curve and the Wp＋C water displacement curve would go up and Lp＋C water displacement curve would slump down at high water－cut stage．
