油水两相流动漂流模型的研究

Study on drift Model of Oil/Water phase Flow

郑希科，谭廷栋，李进旺，等．油水两相流动漂流模型的研究．测井技术，１９９８，２２（３）：１７８～１８２漂流模型考虑了多相流之间在流动特性上的相互影响以及流动机构因素，常常用来整理滞留数据，在研究管道多相流动中得到了广泛应用。对模拟井动态实验数据整理发现，漂流模型在持水率大于０．７５时具有较低的解释精度，在实验数据的基础上对此问题进行了探讨，并提出了新的解释方法。

Since the influence of multi phases on the flowing characters and flowing mechanism factors are considered in drift model, the model is often used to process multi phase flow retention data and has a wide application in the research of multi phase flow in pipe. It is found that the drift model has a lower accuracy when the water holdup is greater than 0 75 in the processing of dynamic experimental data obtained in the simulating well. Based on the experimental data, this problem is discussed and a new interpretation method is proposed.
