| 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. |
