一种新型水驱特征曲线及应用

水驱特征曲线是水驱开发油田固有的特征曲线,对于水驱油田的预测具有重要意义。本文针对甲、乙、丙、丁水驱特征曲线单独使用时预测偏高或偏低的问题,在其基础上,提出了即简单又分别综合了甲型和乙型,丙型和丁型的新型水驱特征曲线,从而扩大了他们的应用范围,提高了预测准确程度。实例计算表明,所建立的新型水驱特征曲线与实践数据拟合相关性更强,结果更可靠。

A New Water Drive Characteristic Curve and Its Application

Water drive curves are the inherent characteristic curves of waterflooding,there are important to waterflooding oil field forecasting.In this paper,because of incorrect when used A,B,C,D water drive characteristic curves alone,based on them,give a new type water drive characteristic curve,it is simple and combine AB water drive characteristic curve,CD water drive characteristic curve,respectively.Thereby,expanding their range of applications and improving forecast accuracy.Practical calculation shows that t...
