广式水驱特征曲线特征参数q值确定方法探讨

Methods of Determining the Value of Characteristic Parameter q of Eurytopic Water-Drive Characteristic Curve

张金庆提出的广式水驱特征曲线比传统的水驱曲线预测精度更高,该曲线表达式中特征参数q的确定非常重要。根据油田实际数据,讨论快速确定参数q的几种方法,如拟合法、类比法、可动油储量标定法等。

Compare with the conventional water drive curve,the eurytopic curve proposed by Zhang Jinqing has higher prediction accuracy,while it is critical to determine the value of parameter q in adopting this curve. Based on the actual data,there are three methods to determine the value of q： fitting method,analogy method and movable oil reserves calibration method.
