摘　　要：为避免底水的锥进而导致水淹,底水油藏的油井一般油层并不会完全打开,此时油层对产能的贡献厚度要大于实际的射开厚度。该文运用数值模拟方法,对油层打开程度进行校正,确定出了打开程度与校正系数的关系,进而使产能公式的预测结果与现场实际产能更相符。此研究成果对底水油藏开发具有理论及现场指导意义。In order to avoid the coning of bottom water,the vertical well in reservoir with bottom water usually does not perforate the whole reservoir.At this time,the real interval in the deliverability design is bigger than the perforated interval. The reservoir perforating level is corrected by using numerical simulation method,the relationship between perforating level and correction coefficient is determined,and the prediction results based on deliverability equation are more consistent with actual deliverability.The results of the study are of guidance significance to development of reservoir with bottom water.
