摘　　要：目前国内外对于水平气井的产能研究较少,而且大部分是通过等效半径法来计算水平气井的产能。通过对Joshi关于水平油井的产能公式的分析,并对其进行修正用来计算水平气井的产能。实际计算表明,修正后的产能计算公式能很好地用来计算水平气井产能。最后就水平段长度对水平气井产能的影响进行分析。There were few methods for studying productivity of horizontal gas wells,and these methods were based on the way of equivalent radius calculation.A new approach was presented for inflow performance calculation for horizontal gas wells.This approach is based on the correction formula of horizontal oil wells.Actual calculation indicates that the correction formula can be well used for horizontal gas wells.The influence of horizontal section length on the producibility is analyzed.
