| 摘 要： | 泡沫流体广泛应用于油井的冲砂洗井作业中，携砂能力是衡量其性能的一项重要指标。利用FLUENT软件中的分散相模型对泡沫流体的携砂能力进行了数值模拟，得到了不同直径的砂粒在泡沫流体中的携砂率和停留时间随环空管道倾角的变化关系，与相同条件下水的携砂性能进行了比较，并进行了定性分析。从模拟结果可以看出泡沫流体具有良好的携砂能力，而且更适合于水平井的冲砂洗井。

| Abstract: | Foam fluid is widely used in sand-flushing operations in oilfield, and prop-carrying capacity of foam fluid is very important. Numerical simulation for prop-carrying capacity of foam fluid was conducted using discrete phase model in FLUENT. The relations of ,sand carrying rate and residence time in foam fluid to inclination angle of annular pipe were given. The prop-carrying capacity of foam fluid was compared with that of water on the same condition, and qualitative analyses were provided. The results show that prop-carrying capacity of foam fluid is much better, and it is especially suitable for sand-flushing of horizontal well. |
