Abstract

Abstract: As more and more horizontal wells are drilled in gas reservoirs，determination of accurate deliverability formulas is of great significance.Because deliverability formulas of horizontal oil wells cannot be directly used for horizontal gas wells，after introducing research progress of horizontal well′s deliverability formulas，deliverability formulas of horizontal gas wells are obtained from improving the deliverability formulas of horizontal oil wells by using the method proposed by CHEN Zhi-hai etc.Through comparing the results of these formulas，Borisov，Renard，Dupuy，LANG Zhao-xin and CHEN Yuan-qian formulas are of higher precision than Giger，Joshi formulas which are widely used in horizontal oil wells.It is of reference for future deliverability study of horizontal gas wells.

Key words: horizontal gas well, deliverability, formula, progress, application
