利用光纤探针试验研究垂直上升管内气、水、油三相弹状流截面相份额的规律。实验结果表明,短时域内平均截面含气率是三相流流型判断的有效方法,同时通过对三相流系统中油水比例的改变,对比它对平均截面含液率的影响,并测定各个工况下的平均液弹长度和平均截面含液率。 Using fiber probe test to study the law of the phase proportion of the three phase slug flow in vertical riser pipe. The experimental results show that the average cross-section gas content in the short-time domain is an effective method for judging the flow pattern of the three-phase flow. At the same time, by comparing the ratio of oil and water in the three-phase flow system, The average length of the liquid bomb under conditions and the average cross-section liquid content.
