摘　　要：为提高葡北油田中高含水期油井压裂经济效益,合理选择压裂井层尤为重要。应用水驱特征曲线预测出油井压裂前可采储量,从而计算出剩余可采储量及可采储量采出程度,通过绘制油井压裂前剩余可采储量及可采储量采出程度与油井压裂后所创经济效益之间关系曲线,寻找出相关规律,进行优选压裂井,再根据精细地质研究成果,在剩余油富集区选择具体压裂层位。经实际应用,取得了较好效果,提高了油井压裂方案符合率,提高了经济效益,进而总结出一套适合葡北油田中高含水期油井压裂选井选层方法,对今后进一步搞好油井压裂增产工作具有指导意义。This paper predicts the recoverable reserves of oil wells before fractured by applying waterflood characteristic curve, so that economic efficiency of fracturing can enhanced (luring the period of high water cut in Pubei oilfield. Based on this, we calculate the recovery percent of reserves for residual recoverable reserves and recoverable reserves, and find out correlation law so as to optimize fracturing wells by means of plotting relation curve between recovery percent of reserves and economic benefit in front and behind fractured. Together with fine geology research, we can define concrete fracturing level in remaining area. The method is suitable for the oil wells during the period of high water cut in Pubei oilfield; on the one hand, it increases the coincidence of fracturing plan; on the other hand, it enhances economic benefit. It is also meaningful to fracturing for oil wells in the future.
