基于诸多学者关于垂直管道气-液两相流漂移模型中分布参数和漂移速度的一般规律的研究，采用理论分析和实验研究相结合的方法，提出了水平井筒气-液两相流漂移模型中分布参数和漂移速度的相关式；依据水平井筒模拟试验段上多相流动实验数据，采用参数模型优化的方法，确定了漂移模型中的待定参数，得出了完整的水平井筒气-液两相流漂移模型。

Based on the research on the law of profile parameter and drift velocity of drift model for two-phase flow in vertical pipeline, theoretical analysis and experimental researches are done to propose the expressions of profile parameter and drift velocity of drift model for two-phase flow in horizontal pipeline, which include four unknown constant parameters. According to the data of multiphase flow experiment in simulation test section of horizontal wellbore, Parameter Optimization Method is used to solve the constant parameters. Finally, complete drift-flux model on two-phase flow in horizontal wellbore is developed.
