摘　　要：在Wiggins针对达西流研究的基础上 ,推导出低速非达西渗流的产能方程 ,为IPR曲线方法在低渗、特低渗透油藏中的应用提供了依据。根据所建立的IPR方程 ,探索了利用多个生产数据或试井数据快速确定启动压力的工程应用。靖安油田长 6特低渗储层的计算结果表明 ,该方法较常规方法更简便 ,且结果可满足工程分析的精度要求。In this paper, based on the Wiggins Darcy fluid research, a productivity equation low velocity non-Darcy fluid is deducted. This equation paves the way for the application of IPR curve method to the low permeability reservoirs. According to this IPR equation, the driving pressure can be determined very quickly by using sufficient production well test data. The results of this method used in Jing'an Chang6 low reservoir reveal that it is simpler than conventional method and can satisfy the precision demand of engineering analysis.
