| 摘 要： | 现场资料表明，注水开发的油井在井底流压很低时，随着生产压差的增大，油井产液量并没有上升，而是下降，其流入动态曲线凹向压力轴，出现一个拐点。本文在考虑流动能力系数的基础上，修正了经典的Vogel方程，建立了新型油井流入动态模型。计算实例表明，当流压低到一定程度后，IPR曲线出现拐点，与现场生产实际情况符合。

| Abstract: | Performance data indicates that the production of waterflooding oilfields doesn’t increase but declines with the production pressure increasing when the bottom-hole flow pressure is very low.And their IPR cures concave to the pressure axis and show a turning point.Considering the flow ability correction coefficient,the classic Vogel equation was modified,and a new IPR model was established.The actual example shows that a turning point appearances in the IPR cure when the bottom-hole flow pressure is lowed to certain extent.This is correspond to the actual situation of on-site production. |
