| 摘 要： | 水驱面积波及效率是影响油藏采收率的重要参数.以江苏油田复杂小断块油藏为例,研究复杂边界油藏水驱面积波及系数的校正方法.应用三维两相黑油模型建立不同油藏边界、不同井网形式的数值模型,计算出根据油藏边界类型定义的窄小油藏复杂边界校正系数与窄条油藏复杂边界校正系数.油田现场可直接根据窄小断块的类型和窄条断块的含油带宽度来选取相应校正值,从而校正水驱面积波及系数,调整开发技术政策.

| Abstract: | Waterflooding areal sweep efficiency is critical to reservoir recovery factor.This paper studies the correction method of areal sweep efficiency for waterflooding reservoirs with complex boundary by taking the complicated minor fault block reservoirs in Jiangsu oilfield as examples.A 3D 2-phase black oil simulator is employed to conduct numerical simulation with different reservoir boundaries and well patterns,thus calculated the correction factors of complex reservoir boundaries such as narrow and striped ... |
