【摘要】：在多相流研究领域,高黏油水两相流已成为研究重点,但该领域的研究仍处于起步阶段。本文从转相、流型转换和压降规律三个方面对国内外高黏油水两相流的研究进展进行了介绍和分析。在转相方面,通过国内外学者的研究阐述了高黏油水两相流转相发生的机理及影响因素;在流型转换方面,介绍了影响分层流和分散流等流型转换的因素;在压降规律方面,分析了影响分层流、分散流和环状流压降规律的因素,并对现有的压降计算模型及压降预测的准确性问题进行了探讨。此外,还重点阐述了高黏油水两相流研究存在的不足与今后研究的两个重要发展方向:一是将实验得到的结论与成果应用于实际管道时应进行相关参数的修正;二是弯管对高黏油水两相流流型转换及转相的影响需要进一步研究,它们对于管道的安全和经济运行具有重要意义。
[Abstract]:In the field of multiphase flow, high-viscosity oil-water two-phase flow has become the focus of research, but the research in this field is still in the initial stage. The research progress of high viscosity oil-water two-phase flow at home and abroad is introduced and analyzed from three aspects of flow pattern conversion and pressure drop law. Through the research of domestic and foreign scholars, the mechanism and influencing factors of high viscosity oil-water two-phase flow phase are expounded. In the aspect of flow pattern conversion, the factors influencing the flow pattern conversion, such as stratified flow and dispersed flow, are introduced. In the aspect of pressure drop law, the factors influencing the pressure drop law of stratified flow, dispersed flow and annular flow are analyzed, and the accuracy of pressure drop calculation model and pressure drop prediction are discussed. The shortcomings of the study of high viscosity oil-water two-phase flow and the two important development directions in the future are emphasized. First, the relevant parameters should be revised when the experimental results and results are applied to the actual pipeline; Second, the influence of bend on the flow pattern transformation and phase transformation of high viscosity oil-water two-phase flow needs further study, which is of great significance to the safety and economic operation of pipelines.

【正文快照】： 在油田开发中,当地层压力不足时,一般采用注水的方式提高地层压力来进行原油开采。近年来,随着国内油田的开发进入中后期,采出液综合含水率逐渐上升[1-2],其采出流体多为高含水原油混合液[3]。油水混合液在集输管道输送过程中,极易形成油水乳状液[4-5]。根据文江波等[6]研究,
