inflow production relation
井底流压-产量关系
The retrograde condensation impact tends to be unavoidable because the phenomenon that bottomhole producing pressure is lower than dew point pressure is easy to be found in productivity well test.
而在产能试井中很容易出现井底流压低于露点压力的情况，因此反凝析现象不可避免。

It is also exist in oil well production when hign flow velocities occurs with flowing bottomhole pressure above saturation( bubble point) pressure.
对于油井,当井底流动压力高于饱和压力时,随着流动速度的增加,湍流同样存在。
