| 摘 要： | 为了提高吉林油田水平井开发深层天然气的产能和经济效益,研究了低渗透率气藏水平井产能影响因素。所考虑的影响因素包括储层渗透率、储层厚度、水平段长度、纵向位置、表皮系数、压裂裂缝条数。研究表明:在相同渗透率下,随着水平井段长度、气层厚度和压裂缝条数的增加,水平井采气指数增加,而且三者对水平井采气指数的影响显著;水平井采气指数随表皮系数的增加而降低幅度逐渐减缓;纵向位置影响甚微;水平井采气指数随着储层渗透率的增大而逐渐增大。

| Abstract: | The influential factors of horizontal well productivity in low permeability gas reservoir have been studied for the Jilin oilfield to improve deep gas development.The influential factors include reservoir permeability,reservoir thickness,length of horizontal segment,vertical location,skin factor,and the number of induced fractures.The results show that under same permeability,the gas productivity index(PI) of horizontal well increases with the increasing of the length of horizontal segment,gas layer thickne... |
