川渝地区带状气藏分支水平井的产能公式——齐成伟公式的推广
|
摘要
齐成伟公式是国内外首次出现的建立于带状油藏的水平井产能预测公式,但不适用于气藏。为了预测川渝地区带状气藏中分支水平井的产能,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,成功地将齐成伟公式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,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。建议将齐成伟的圆形油藏中辐射状分支水平井拟三维产能公式推广到圆形高含硫气藏中。
Qi Chengwei's formulae consists of the two formulae for predicting horizontal well productivity, proposing at first time in the world; the formulae is only for the prediction of ribbon-shaped petroleum reservoir, but not for the prediction of natural gas reservoir. In order to predict the productivity of branched horizontal well in ribbon-shaped gas reservoir in the Sichuan-Chongqing region, according to the similarity principle between gas seepage and liquid seepage and the relationship between gas relative permeability and sulfur saturation summed up by Roberts, the famous Qi Chengwei's formulae are successfully generalized to pseudo three-dimensional productivity formulae of horizontal well in ribbon-shaped sour gas reservoir. On the basis of the revised formulae, the impact of sulfur deposition amount and permeability anisotropy coefficient on productivity is analyzed, and important knowledge that the effect of sulfur deposition amount on productivity is greater than that of permeability anisotropy coefficient is obtained and longitudinal bilateral horizontal well possesses more advantages than transverse horizontal well in ribbon-shaped sulphuric gas reservoir. At last, a proposal that the pseudo three-dimensional productivity formula derived by Qi Chengwei for radial branched horizontal well in circular petroleum reservoir should be promoted to sulphuric gas reservoir is put forward.
