    Abstract：Advantages of horizontal well in low-permeability and compacted gas reservoir development have become more and more prominent with the technological progress in transformation process of horizontal well reservoir and at present， horizontal well has become important means in low-permeability and compacted gas reservoir development. However， due to complex wellhole trajectory and flow pattern of horizontal well， conventional prediction model is not suitable for its critical liquid-carrying flow prediction， such prediction has become a key puzzle for horizontal well liquid discharge. Therefore， adopted is the visual gas-liquid two phase simulator of horizontal well pipe flow and applied is the segmented simulation method to correct critical liquid-carrying flow prediction model of slope sections and horizontal sections according to a large number of flow simulation experiment results and establish a correction model for critical liquid-carrying flow prediction of horizontal well. The model has been applied in the site and good results have been achieved.
