摘　　要：通过对分散泡状流流型中的分散气泡进行受力分析 ,考虑了管壁入流或出流的影响 ,得到水平井筒气液两相变质量流动分散泡状流向间歇流流型转变的判别方法。并分别应用气、液两相质量守恒方程和动量守恒方程 ,考虑管壁存在入流或出流对于分散泡状流流型压降的影响 。This paper analyzes the force of dispersal foam in dispersal bubble flow combining with the effect of the inward and outward flow of the pipe wall, and obtains a determination method for dispersal bubble flow turning into intermittent flow. It uses two phases mass conservation equation and momentem conservation equation considering the effect of inward and outward flow in the pipe wall, and obtains a calculation method for dispersal bubble flow types.
