摘要
【问题】针对复杂边界油气藏中分支水平井的产能预测问题进行了深入研究。【方法】根据齐成伟建立的圆形油气藏中辐射状分支水平井拟三维产能公式,【结论】得到了扇形油气藏中水平井的拟三维产能公式;【方法】根据齐成伟建立的带形油气藏中横向水平井拟三维产能公式,【结论】得到了带形油气藏中顶壁横向水平井的拟三维产能公式;【方法】根据齐成伟建立的带形油气藏中纵向双分支水平井拟三维产能公式,【结论】得到了带形油气藏中(单分支)水平井、半带形油气藏中顶壁纵向水平井、半带形油气藏中离壁纵向水平井的拟三维产能公式。【意义】该研究拓展了分支水平井拟三维产能公式的应用范围,丰富了产能预测理论。
Productivity formulae for branched horizontal wells derived by QI-Chengwei were analyzed in this paper.Firstly,the pseudo-3-D productivity formula for radial multi-lateral horizontal wells in pie-shaped reservoir in the application of fan-shaped reservoir was expatiated.Secondly,the pseudo-3-D formulae for predicting productivity of transverse and longitudinal double-lateral horizontal wells in ribbon-shapedreservoirs were expounded.Finally,a new system of formulae for predicting productivity of branched horizontal wells was established.
