The judgment of flow pattern in the wellbore of a liquid-producing gas well is very important to the judgment of its liquid-carrying capacity in the production process. Through mathematical fitting of duns- ROS flow pattern of vertical well, Gould flow pattern of inclined well and Goiver flow pattern of horizontal well, the different flow pattern is fitted into 3, 4 and 4 curves respectively, and divided into 9, 10 and 20 regions respectively. The division standard among different regions is given, optimized parameters are selected, and a VB software is edited. The results show that the software fitting effect is accurate, and can be well applied to the actual flow pattern judgment.
