摘　　要：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。An optical fiber probe is used to study the cross-section of oil-gas-water three-phase slug flow in verti- cal tubes. The result shows that short-time-averaging void fraction is effective method on flow pattern recognition. Meanwhile,by changing the ratio of oil to water in the three-phase flow system,its influence on averaging cross-section liquid holdup is found out. The averaging liquid lengths and averaging cross-sec-tion liquid holdup are obtained in each case.
