摘　　要：在进行水驱特征曲线的拟合过程中发现一种新型水驱特征曲线,通过变形后发现是西帕切夫水驱特征曲线的修正。经过理论推导给出了新型水驱特征曲线预测不同含水率下油田的采油速度以及技术可采储量的计算公式,利用现场的实际数据进行了可采储量的计算,并与其他5种常用的水驱特征曲线的计算结果进行对比,结果表明,该曲线预测值可达到较高的精度。During the matching of water-drive type curves,a new type curve is found,and this is a modification of N.V.Sipaqiev＇s curve following transformation.After theoretical derivation,the calculation formulas in term of the new water-drive type curve are presented for prediction of the oil recovery rate and technical recoverable reserves in different water cuts.The recoverable reserves are calculated based on the actual data and the result from this curve is compared with ones from other five conventional type curves.The results show that the predicted value from this curve can give higher accuracy.
