油气水三相流压降理论研究进展

Progress in Theory Research of Pressure Drop of Oil-Water-Gas Three-phase Flow

介绍了国内外近20年来油气水三相流压降理论研究的进展,分析了主流的两种三相流压降理论,即基于气液两相流相关式模型的三相压降理论和基于力学模型的三相压降理论,指出了两种压降理论的适用范围和存在的问题,提出了将三相流压降理论的研究同油水反相规律研究相结合的发展思路。

With the development and exploitation of oilfields,the simultaneous flow of oil,water and gas become a common phenomenon in transportation pipelines,which would make the transporting process much more complicated.Due to the development of offshore oilfields,the transportation technology of oil-water-gas three-phase flow has been the spot at home and abroad since the 1980' s.During the design of three-phase pipelines,the hydraulics calculation,especially the theory of pressure drop calculation,is major factor to be considered.This paper summarizes the research achievements of pressure drop calculation theory in three-phase flow,points out the problems and difficulties which are demanded further researching as well,with the purpose of guiding reference for further research in this field.
