摘　　要：根据气相渗流与液相渗流的相似原理和Roberts气体相对渗透率与含硫饱和度关系,著名的齐成伟带横公式被成功改造为带状高含硫气藏中横向水平井的拟三维产能预测公式。根据齐成伟带横公式的高含硫气藏修正公式,分析硫沉积量、渗透率各向异性系数、带状气藏长度、生产段井筒位置和生产段长度对产能的影响规律后,取得了硫沉积量对产能的影响大于渗透率各向异性系数的重要认识。According to the similarity principle between gas seepage and liquid seepage and the relationship,summed up by Roberts,between gas relative permeability and sulfur saturation,the famous QI-Chengwei’s formula were successfully generalized to pseudo three-dimensional productivity formula of horizontal wells in ribbon-shaped Sour Gas Reservoir.On the basis of the revised formula,the impact of sulfur deposition amount,permeability anisotropy coefficient,length of gas reservoir,position of productivity section,length of productivity section on productivity was analyzed,and important knowledge was obtained that the effect of sulfur deposition amount on productivity is greater than that of permeability anisotropy coefficient in ribbon-shaped Sour Gas Reservoir.
