摘　　要：通过矿场资料的统计分析 ,探讨、揭示了连续生产油井采油指数的下降规律。在此基础上 ,建立了利用井底流压、产油量与累积产油量直接预测油井供给边界压力的新方法。本文方法思路清晰、原理正确 ,充分发挥了流压监测资料的作用。应用实例表明 ,该方法具有预测精度较高、应用简便的特点 ,可作为常规动态分析方法的重要补充。By means of statistical analysis of field data,this paper discusses and reveals the decline law of oil production index of continually producing wells.Based on the law,a new method to predict the drainage pressure directly by flowing pressure,oil production and cumulative oil production is found.This method has a clear train of thought and a correct principle ,and it takes full use of flowing pressure testing data.The actual applications show that this method has the features of a high accurate degree and easy to apply,it can be used as an important supplement method for conventional performance analysis.
