齐成伟公式之于带状含硫气藏水平井产能预测
|
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的关系,将齐成伟公式成功改造为带状高含硫气藏中分支水平井的拟三维产能预测公式。根据齐成伟公式的高含硫气藏修正公式,在分析硫沉积量和渗透率各向异性系数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、在带状高含硫气藏中宜打纵向双分支水平井的重要认识。
In order to predict the productivity of branched horizontal well in ribbon-shaped gas reservoir, according to the similarity principle between gas phase seepage and liquid phase seepage and relation between gas relative permeability and sulfur saturation summed up by Roberts, Qi Chengwei's formula are successfully generalized to pseudo three- dimensional productivity formula of horizontal well in the ribbon-shaped high sour gas reservoir. On the basis of the modified formula, the impact of sulfur deposition amount and permeability anisotropy coefficient on productivity are analyzed, and important knowledge that the impact of sulfur deposition amount on productivity is greater than that of permeability anisotropy coefficient is obtained and the longitudinal bilateral horizontal wells possesses more advantages than transverse horizontal well in ribbon-shaped sour gas reservoir.
