应用Usher模型预测单井含水率变化

Prediction of the variation of single-well water-cut using Usher model

准确预测单井的含水率变化趋势,对决策单井下步采取何种措施具有重要意义.根据单井含水率随井底流压变化的规律,对广泛用于经济和资源预测的Usher模型,经适当改进,并引入无因次压力概念,用于预测单井含水率的变化.经现场实例验证具有很好的实用性和有效性.

The prediction of the variation of single-well water-cut is of importance to the further measures of the well.Usher model is used for the purpose by improving the model and improving a dimensionless pressure.A field test shows that the prediction method of single-well water-cut is practical and effective.
