摘　　要：根据水平井筒和常规水平管道中气液两相流动的相似和差别 ,可知常规水平管流的流型转换标准用于井筒流动需要进行修正或扩展。根据气液两相界面波的迅速成长机理 ,考虑了管壁存在入流或出流对于分层流向非分层流流型转变的影响 ,在Taitel&Dukler的研究基础上 ,得到水平井筒气液两相变质量流动分层流向非分层流流型转变的判别方法。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 。Due to similarities and difference between gas liquid two phase flow in a regular horizontal pipe and in a horizontal wellbore, it is anticipated that some transition mechanisms valid for regular pipe flow need modification or extension for wellbore flow. According to the mechanism of the rapid growth of waves, considering the influence of wall inflow/outflow, obtain a method to judge the transition from stratified to non stratified flow pattern of gas-liquid two-phase variable mass flow in horizontal wellbore,and a new method to judge the transition from dispersed bubble to intermittent flow pattern of gas liquid two phase variable mass flow in horizontal wellbore by force analyzing of dispersed bubble.
