Review of the Study on Oil-water Two Phase Flow Patterns in Horizontal Pipelines

As an important branch of the field of multiphase flow, the phenomena of oil-water two-phase flow widely exists in each aspect of the oil industry. The study of oil-water two phase flow patterns in horizontal pipelines is of great significance to solve the important technical problems in oil production. In this paper, the domestic and international research history of the oil-water two phase flow patterns in horizontal pipelines have been summarized, and the division methods of flow patterns were introduced. The major factors and parameters affecting the flow patterns have been analyzed, including velocity and phase holdup, viscosity of oil phase, the diameter and material of pipe, entrance shape and additives. Several measurement methods for flow pattern parameters and flow pattern identification methods were introduced, and the disadvantages of the existing measurement methods were also analyzed. The existing problems and direction in the research were proposed for the oil-water two phase flow pattern study in the future, including the further study of influencing factors, measurement methods and internal structure of the flow pattern.
