| 摘 要： | 综合考虑了水平井筒完井段生产、各条裂缝长度不等、导流能力不同、间距不等、与水平井筒夹角不等以及关于井筒非对称等因素对产量的影响,建立了压裂水平井裂缝分段入流、水平井筒分段入流与油藏渗流的耦合模型.通过实例计算,揭示了水平井筒完井段及裂缝段的入流和压力分布规律,并对各裂缝的产量进行了敏感性分析.结果表明,在裂缝与井筒交点附近,裂缝入流存在局部极大值,且生产压差最大;裂缝之间的水平井筒完井段入流速度存在极大值,在裂缝与井筒交点处压力变化幅度剧增;裂缝半长对外裂缝产量影响程度深,对內裂缝的影响相反.

| Abstract: | A coupling model of subsection inflow of fractures, subsection inflow of horizontal conduit and percolation was developed in reservoir, which considered the influence of horizontal wellbore inflow, varying half-length of every fracture lf , varying spacing of every fracture, varying flow conductivity of every fracture, varying angle between fracture and wellbore of every fracture, asymmetry of fractures on output.The inflow and pressure law alone fracture and horizontal wellbore was obtained by a calculatin... |
