摘要(Abstract)：

油田进入高含水后期,油水运动规律复杂,剩余油分布零散,目前尚没有一种有效的具体到井点的剩余油预测方法。在研究了一种模拟射孔法的基础上,通过宏观控制、微观解剖、潜力定量和单井确定等四个环节,采用资料统计法、神经网络辅助法和虚拟井位射孔法三种方法,可预测出三次加密布井空白区的可调厚度,通过打井验证精度达85%以上,并根据预测结果可将新布井分为有效井、低效井和风险井。这一方法可将三次加密可调厚度预测精度由原来的70%左右提高到85%以上,为三次加密调整布井提供了一种既实用又有效的方法。
In the later stage of high water cut, the oil and water movement is complex,and the remaining oil distribution is dispersed. There is still not an effective method for remaining oil prediction. This paper studies an analogue perforation method. Through macro controlling, micro profiling,potential quantification and single well determination,it can measure the adjustable thickness of the blank area of the tertiary infilling arrangment using data statistics, neural network and virtual well location perforation methods. Drilling practice proves the accuracy of more than 85%. According to the prediction, the newly arranged wells are classified into effective wells,low effective wells and risk wells. This method can increase the prediction accuracy of the adjustable thickness of the tertiary infilling from 70% to 85%.
