摘要
Y1型水驱特征曲线比一般的水驱特征曲线适用性广而强,要求参数少,计算简单快速。通过对某底水油藏水平井含水上升规律进行研究,发现Y1型广义水驱特征曲线在计算低含水期的含水上升规律时,单井预测偏差过大。通过对Y1型水驱特征曲线进行初始含水率条件限定,在底水油藏水平井动态预测中得到更令人满意的效果。
Type-Y1 water drive characteristic curve is of wider applicability, less parameter required, simpler and quicker calculation than general water drive characteristic curve. This paper studies the rising regularity of water cut in horizontal well in a bottom water reservoir, and presents that the single horizontal well prediction of water cut is on the large deviation using this curve for calculation of the low water-cut stage. By means of limiting the initial water cut of this curve, the performance prediction of the horizontal well in bottom water reservoir is then more satisfactory in effectiveness.
