新型水驱特征曲线系列

NEW STYLE WATER DRIVE CHARACTERISTIC CURVE SERIES

针对目前在国内用得比较多的水驱特征曲线只能对应一类fw～R*曲线、广义水驱特征曲线可以反映各种类型的fw～R*关系曲线,但表达式比较复杂、参数不易求解,不便于应用。在前人研究的基础上提出了一种既简单又综合了甲乙两种类型关系的fw～R*水驱特征曲线。实例计算表明,所建立的新型水驱特征曲线与实际数据拟合相关性更强,结果更可靠。对水驱油田的预测可采储量和产量具有重大价值。

The water drives characteristic curve aimed at domestic use can only deai withfw～R curve, the common water drive characteristic curve can reflect all types of fw～R relation curve, but the expression is complicated, the parameterse difficult to solve, and not suitable for practical use. On the basis of existed research, a simple fw～R water drive characteristic curve integrating two types of relations is put forward. Practical calculation shows that the established new type of water drive characteristic curve matches practical data better, result is more reliable, and better value is demenstrated to the predicted recoverable reserve and productivity of water drive reservoirs.
