油井产出物的多相流输送是制约卫星油田发展的重要因素。本文讨论了多相流的主要特点及分析方法，并讨论了了解及预测多相流行为所遇到的问题。文中给出了BHRGROUP在研究过程中解决这些问题的实例，给出了确定现存软件模型边界条件及置信水平的建议，强调了需深入研究以确定多相流所遇到的关键参数的作用。 Multiphase flow delivery of oil well products is an important factor restricting the development of satellite oil fields. This paper discusses the main features and analytical methods of multiphase flow, and discusses the problems encountered in understanding and predicting multiphase flow behavior. This paper presents examples of BHRGROUP addressing these issues in the research process, presents recommendations for determining the boundary conditions and confidence levels of existing software models, and emphasizes the need for further research to determine the key parameters encountered in multiphase flow.
