摘　　要：分相流技术把分相流概念应用于油井正常生产过程中,在评估可采储量时,油井不关井以相同或相近的方式继续生产。该方法给出所有油井井底的平均含水饱和度(出口端)与含水率之间的关系曲线。通过油井计算可以得到石油可采储量,应用这个曲线可以评估其最终总可采储量。应用分相流理论模型对油田经济可采储量进行预测,可以在油田不关井的情况下进行预测,避免了油田关井的损失。从羊二庄油田与龙虎泡油田的应用实例中,分相流预测模型都得到了很好的结果。证明该模型容易掌握、计算简便、精确度高。Phase flow technology applies the concept of split-phase flow for normal production wells process in the assessment of recoverable re- serves; the oil wells continue to produce in the same or similar ways without closing. This method gives the relationship curve of the average water saturation （outlet） of all the well bottoms and moisture content. Oil recoverable reserves of oil can be got by calculating, and this curve can be used to evaluate the fi- nal total recoverable reserves. Phase flow theory is applied to predict economic recoverable reserves of the oil field. Prediction is carried out without shutting oil fields to avoid loss of shut-in oil well. From Yangerzhuang and Longhupao oilfield instances, phase flow prediction models have very good results, prov- ing that the model is easy to grasp and calculate, and is highly accurate.
