摘　　要：为改善井筒中三相流流型划分不精确的实际状况,本文采用室内实验与理论研究相结合的方法针对不同倾角、气液比工况下井筒中油气水三相流型开展了详细研究。通过分析研究发现,不同工况下倾斜管及垂直管中油气水三相流流型总体上呈现气泡流、段塞流、搅动流、环雾流四种流型;基于此建立了油气水三相流流型划分综合有效模型,并明确了泡状流–段塞流、段塞流–搅动流、以及搅动流–环雾流的流型转换界限模型;通过实验数据检验该模型发现研究得出的不同倾角流型划分方法与实验结果吻合良好。本研究中油气水三相流流型划分综合方法可为井筒中油气水三相流流型划分及压力预测提供依据。In order to improve the actual situation of inaccurate division of the three-phase flow pattern in the wellbore, this paper uses a combination of laboratory experiments and theoretical research to carry out a detailed study of the oil-gas-water three-phase flow pattern in the wellbore under different inclination angles and gas-liquid ratio conditions. Through analysis and research, it is found that the three-phase flow patterns of oil, gas and water in inclined pipes and vertical pipes generally present four flow patterns of bubble flow, slug flow, agitation flow and annular mist flow under different working conditions. A comprehensive and effective model for the division of phase flow and flow pattern was established, and the flow pattern transition boundary models of bubble flow-slug flow, slug flow-stirring flow, and agitation flow-annular mist flow were clarified. The obtained flow pattern division method with different inclination angles is in good agreement with the experimental results. The comprehensive method of the three-phase flow pattern division of oil, gas and water in this study can provide a basis for the flow pattern division and pressure prediction of the three-phase flow pattern of oil, gas and water in the wellbore.
