摘要
针对国内外井涌理论中存在的问题，对空气－水、空气－泥浆两相流系统进行了实验研究．用垂直环空管流实验架、井眼数据测量与传输遥测系统，以及计算机实时数据采集系统，获取了大量实验数据．在此基础上，绘制了空气－水、空气－泥浆两相流的流型图，并利用回归分析的数学方法获取了空气－泥浆两相流泡状流向弹状流过渡的过渡区数学模型．
This paper presents some experimental results of air-water and air-mud two-phase flow in a vertical annular simulator. A real time data acquisition system, data measuring and transmitting telemetering were used to acquire a lot of data. Based on these data. the flow patterns of air-water and air-mud were given. The calculation models for local void fraction changed from bubble flow to plug flow of air-mud two-phase flow were obtained.
