摘要
综述了水平井筒沿管壁具有流体流入的变质量流动的最新研究进展．内容包括：考虑油藏流体流入时井筒流动压力及产量的计算，具有不同流入时管壁摩擦系数的经验计算公式，以及流体径向流入井筒后流动阻力损失产生的机理分析等．重点介绍了水平井筒变质量流动阻力系数的计算，同时文中还介绍了井筒两相变质量流动损失产生的机理和数值模拟研究进展．
This paper reviews the latest advances on the variable mass flow with wall inflow in horizontal wellbores. The discussions mainly focus on the following topics: the calculation of the horizontal wellbore flow pressure and the oil output; the formula for wall frictional factor correlation with various influx; and the mechanical analysis of flow resistance loss within the wellbore with radial inflow. Especially, the calculation of flow resistance factor of variable mass flow in introduced. The mechanism of the flow loss of two-phase variable mass flow and the advances on the numerical simulation of horizontal wellbores are also discussed.
