摘　　要：论述了深井气举采油的工作特点，阐述了气液两相管流研究对气举井设计和运行的重要作用，从研究方法上综述了国内外铅直气液两相管流的研究现状，分析了铅直气液两相流研究中尚存在的不足以及应用上的局限性，指出应加强铅直气液两相管流基础应用研究，提出适合我国的空隙率、混合液密度、压力梯度相关式。还针对气液两相流动特点和流动型态的多样性，提出应采用模糊数学方法来研究气液两相流的流动型态，以得到合理而科学的气液两相流分类公式和方法。This paper discusses the operating features of deep-well gas-lift, and describes the important role in the design and operation of gas-lift well. B ased on research methods, the paper gives a literature survey of present study s ituation of gas liquid two-phase flow in vertical tubes in the world, and analys es the issues existing in them and limitations in their applications. On the bas is of this, the authors point out that we should strengthen the research of gas liquid two-phase flow in vertical tubes, and put forward the void fraction、two- phase density and pressure gradient correlation of ourselves. In order to obtain a reasonable and scientific classification, the authors also point out that we should study flow regime of gas liquid two-phase flow by using fuzzy set method s according to the flow features and variety of flow regime of gas liquid two-ph ase flow.
