摘要: 油藏数值模拟模型的初始化是油藏数值模拟过程中的重要环节。而常规的平衡法会导致在油层大片连通的区域有完全相同的原始含油饱和度值,这不符合真实的油藏流体分布情况。为提高数值模型的精确度,提出了枚举平衡法进行油藏数值模拟的模型初始化,原始流体饱和度通过三维地质模型的饱和度进行枚举,不再取决于相渗曲线端点值;然后通过相渗曲线端点标定,生成新的相渗曲线;通过毛管压力标定,保证了初始状态时流体饱和度场的平衡。实际应用表明,枚举平衡法能够较好地展示油藏原始含油饱和度的真实分布状态,并减少历史拟合工作量,在油藏数值模拟的实践中有较好的应用效果。

Abstract: The initialization of reservoir numerical simulation mode is very important to the model. The equilibrium method commonly used may result in the same initial oil saturation for a large connectivity area, which is different to the real condition. For improving the accuracy of the simulation model,the initialization by enumeration equilibrium method was proposed. The initial saturation is enumerated from 3D geological model and no longer depends on the end point values of the relative permeability curves. Then the end point scaling method is used for the relative permeability curves,and the new curves are produced. The initial liquid equilibrium-requirements can be met by capillary pressure scaling. The results show that the initial oil saturation distribution gained by enumeration-equilibrium method is closer to the true condition,and the history match can be simplified. The approach works well in application on reservoir numerical simulation.
