In a reservoir with a bottom water boundary, the flow regimes are: well bore radial flow → transitional flow → steady flow;

在底水油藏中，水平井流动期为井筒径向流→过渡流→稳态流；

The fractal dimension of the fluctuations are lower than 1.5 in all flow regimes besides the annular flow with great gas superficial velocity.

实验发现环状流区高气速时的压差波动分维数大于1.5 ，在其它流型内都小于1.5。

It is demonstrated that the predicted results of the mean flow parameters are very sensitive to the eddy viscosities that are dependent on flow regimes.

通过模拟结果和文献数据的对比分析表明，环流速度与塔内液相的流型密切相关。
