水驱特征曲线是油藏工程的一个很重要的方法．针对安塞油田王窑区渗透率很低、中低含水的现状，选择了一种适合于该区块的水驱特征曲线，并利用单井水驱特征曲线，对该区的３５口油井的单井控制储量、可采储量、剩余油饱和度以及采收率进行了标定．在分析对比的基础上，将该区的水驱特征曲线分为两种类型．水驱特征曲线计算结果表明该区的单井控制储量、可采储量、单井采收率都比较小，剩余油饱和度比较大，且各参数在单井间的变化不是很大
The water drive characteristic curve is a very important method for reservoir engineering. According to the low permeability and low and medium water content in the Wangyashan area of Ansai Oilfield, a waterflooding characteristic curve suitable for this block was selected. Based on the single-well waterflooding characteristic curve, Single well control reserves, recoverable reserves, remaining oil saturations and recovery rates were calibrated. Based on the analysis and comparison, the waterflooding characteristic curves of the area are divided into two types. The calculation results of waterflooding characteristic curves show that the single well control reserves, recoverable reserves and single well recovery rates are relatively small and the residual oil saturation is relatively large in this area, and the variation of each parameter among single wells is not very large
