安塞油田王窑区水驱特征曲线及其应用

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

Water Drive Characteristic Curve of Wangyao Tract in Ansai Oil Field and Its Application

In accordance with low permeability and low middle water cut of Wangyao tract in Ansai Oilfield,a suitable type of water drive characteristic curve is chosen for this tract.And by means of the water drive characteristic curve of single well,respective oil in place,recoverable reserve,remaining oil saturation and recovery factor of 40 oil wells in the tract are calibrated.The results show that oil in place,recoverable reserve and recovery factor of single well are less,remaining oil saturation is higher,and there is a little difference in the parameters of each well.In addition,by analysing and comparing,the water drive characteristics curves in the tract are divided into two classifications.
