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.
