摘要
基于等效井径模型、裂缝内线性流动模型、井筒变质量流动模型,运用势叠加原理,建立了压裂水平井油藏渗流与井筒管流耦合模型。研究分析了裂缝参数对其压裂水平井产能影响规律,并运用灰色关联因素分析方法,给出了裂缝参数对其产能影响的重要性排序方法,解决了压裂水平井裂缝参数重要性排序问题。同时该耦合方法可以推广应用到多分支复杂结构井的油藏渗流与井筒管流的耦合。
Based on the model of equivalent hole diameter, the model of linear flow in the fissure, the model of variable mass in the wellbore and the principle of potential superposition, a coupling model of seepage flow in the reservoir and conduit flow in the wellbore for fractured horizontal wells was established. The influence of fissure feature parameters on the productivity of fractured horizontal wells was analyzed. With Grey Correlation Analysis a ranking method of fissure feature parameters which has important influence on the productivity was given. Also the coupling model can be used to apply to coupling of seepage flow in the reservoir and conduit flow in the wellbore for multi-lateral wells.
