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.%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，得到水平井筒气液两相变质量流动分散泡状流流型的 压降计算方法。
