摘　　要：在油井采出液的开采、集输和处理过程中,普遍存在油气水三相流流动现象。当油田进入高含水开发期后,随着含水率的升高和气液比的降低,气相的影响显著降低,油水两相的流型变化对管输效率影响较大。通过按原油凝点划分,将不同学者对油水两相流流型的相关研究从高于凝点温度和低于凝点温度两方面进行分析梳理,总结归纳油水两相流流型研究现状,并结合室内试验研究中存在的问题和不利条件,对今后两相流的研究方向提出了一些建议和展望。Three-phase flow of oil,gas,and water often exists in oil well production fluids during stages of excavation,transportation,and treatment.When oilfield development has entered the late stage,high water cut,under the effect of high water content and low gas-to-fluid ratio,the gas-phase’s influence over transportation pipeline efficiency significantly decreased while oil-water two-phase flow’s influence increased.This paper summarized different scholars’research on oil-water two-phase flow based on above or below condensation point of crude oil,and discussed the existing problems and obstacles in laboratory experiments.It put forward suggestions for future research on this topic.
