摘　　要：水驱曲线是注水开发油田固有的特征曲线。文中以水驱油两相流动的非活塞线性理论模型为基础 ,导出了一种新型水驱曲线方程 :Np =A -B/ (Lp+C) 0 .5。理论研究表明 ,新型水驱曲线方程的系数A与油藏的可动油储量Nom有着密切的联系 ,即Nom =A ;系数B与油藏的石油地质储量N有着密切的联系 ,即N =a×B2 /3,并用实例对理论研究结果进行了验证。与目前常用的各水驱曲线方程相比 ,新型水驱曲线方程具有更高的精度。Water drive curves are the inherent characteristic curves of waterflooding. Based on the non-piston linear theory model of two-phase flow, a new water drive curve is derived, i.e. Np=A-B/(Lp+C) 0.5 . Theoretical study show that the coefficient (A) in the new water drive curve equation is closely correlated with reserves that can be put into production (Nom), i.e. Nom = A, while the coefficient B is in close relation with reserves in place (N), i.e. N=a B 2/3 . Examples are given to verify theoretical study results. The new water drive curve equation has higher accuracy than that of the current commonly used equations.
