| 摘 要： | 为了探索和提高吉林油田水平井开发深层天然气的产能和经济效益,必须进一步研究影响其产能的影响因素。通过科学的抽象,建立了反映气藏地质特征的非均质地质模型,以油藏数值模拟为手段,研究了水平井在低渗透率气藏中的产能变化,建立了水平井初期产能与影响因素的定量关系图版。所考虑的影响因素包括储层渗透率、储层厚度、水平段长度、表皮系数、压裂裂缝条数。研究表明:水平井段长度的增加,水平井采气指数增加;随着气层厚度的增加,气藏渗透率对水平井采气指数的影响越明显;渗透率越大,水平井采气指数随表皮系数的增加而降低得越明显;随着压裂缝条数的增加,水平井采气指数增加,但增加的幅度则随着压裂缝条数的增加而减小。
