随着水驱开发油田开发进入高含水期,油田后期开采难度加大,为实现油田的保产稳产需要进行油田的剩余油分布研究从而实现油田进一步的挖潜。采用流管法以实现油田剩余油分布数值模拟研究。建立了一注一采以及反九点法井网概念模型,结合 B-L 方程求解,绘制了相应概念模型的渗流模板,说明了运用渗流模板进行水驱开发油藏开发效果评价方法。分别分析了一注一采以及反九点法面积井网概念模型饱和度场,与床用数值模拟软件结果进行对比,进一步验证说明流管法进行油田数值模拟研究的可行性。选取某实际区块进行流管法数值模拟研究并且与传统数值模拟方法进行对比分析,说明流管法在进行油田开发剩余油分布分析方面的适用性。
隨著水驅開髮油田開髮進入高含水期,油田後期開採難度加大,為實現油田的保產穩產需要進行油田的剩餘油分佈研究從而實現油田進一步的挖潛。採用流管法以實現油田剩餘油分佈數值模擬研究。建立瞭一註一採以及反九點法井網概唸模型,結閤 B-L 方程求解,繪製瞭相應概唸模型的滲流模闆,說明瞭運用滲流模闆進行水驅開髮油藏開髮效果評價方法。分彆分析瞭一註一採以及反九點法麵積井網概唸模型飽和度場,與床用數值模擬軟件結果進行對比,進一步驗證說明流管法進行油田數值模擬研究的可行性。選取某實際區塊進行流管法數值模擬研究併且與傳統數值模擬方法進行對比分析,說明流管法在進行油田開髮剩餘油分佈分析方麵的適用性。

The water flooding oilfield has entered high water cut period, the exploitation becomes more and more difficult at the late stage of oil field development, in order to keep stable and high productivity and tap the potential of the remaining oil, study on the remaining distribution rule is demanded. In the paper, stream-tube model was established to conduct numerical simulation research on the oilfield remaining oil distribution rule. One injection well and one production well conceptual model and nine-spot patterns were established, combined with B-L equation, seepage template was drawn, and the method to evaluate the water flooding development using the template was elaborated. Water saturation fields of the two conceptual models were drawn and contrasted with ECLIPSE to prove its validity. Actual oilfield block numerical simulation was conducted using the stream-tube model and contrasted with common method to prove its validity in actual oilfield numerical simulation study.
