摘要： 张金庆提出的广义水驱特征曲线表达式, 即WP /NP =-a+b(WP /N2P)关系式形式简单、参数求解容易、反映不同含水上升规律的特性优良、表示油田调整效果敏感、适用性强,是迄今为止最优的水驱特征曲线。它的提出具有很大的理论意义与实用价值。作者提出了应用这种水驱特征曲线计算逐年可采储量的方法, 推导了这种水驱特征曲线对应的油水渗流特征关系,从而对这种水驱特征曲线的研究更加完整和全面。

Abstract: The application of a new generalized water drive curve proposed by Zhang jinqing, Wp/Np =-a +b(Wp/N2p), shows that its shape is simple, to obtain its parameters is easy, characteristics for reflecting different laws of water cut raising are very good, for adjustment of oilfield it is sensitive and its applicability is wide, is the best one so far .Its advance has great theoretical sense and useful velue .A method for calculating recoverable reserves year by year using the water drive curve has been proposed .The formula of characteristics of oil-water seepage flow according to the water drive curve has been derived .So the study for the water drive curve become more complete and more overall .
