基于流管法的油藏数值模拟研究

Reservoir Numerical Simulation Based on Stream-tube method

采用经典B-L方程求解,运用流管法将油藏平面二维两相流动问题转化为一维沿流管两相流动问题。建立了一注一采流管法数值模拟概念模型,绘制了流管法一注一采水驱开发的渗流模板,说明了运用渗流模板进行水驱油藏开发的注采关系调整、水驱动用情况分析以及剩余油挖潜的方法。绘制了一注一采水驱开发饱和度场图,与商业应用软件Eclipse结果进行对比,说明了运用流管法进行数值模拟研究的适用性。建立流管法数值模拟实际模型进行模拟研究,与传统数值模拟方法结果进行对比分析,说明了流管法在进行油田实际开发效果评价方面的适用性。

The stream-tube model was used to change the oilfield two-dimensional and two phase flooding into one-dimensional flooding which can be solved by B-L equation. One injection well and one production well stream-tube numerical simulation conceptual model was established, the template was drawn. The method of using the template to adjust water flooding oilfield injection-production relationship, analyze water flooding degree and further explore residual oil was instructed. The model＇s viability was testified by contrasting with software ECLIPSE. In addition actual model was established and its viability in actual oilfield was also testified.
