| 摘 要： | 目前通过油藏数值模拟的方法计算油层的含油饱和度分布存在工作量大、计算周期长等缺点,不利于快速评价油层的剩余油饱和度分布。为此,提出了一种简单、方便的计算方法快速评价注水开发油田油层的剩余油饱和度分布,即通过计算注水井周围的含水饱和度平面分布,折算出含油饱和度。利用该方法计算双河油田Ⅷ油组1-1层上部剩余油饱和度,与数值模拟结果相对比,两者基本吻合。

| Abstract: | Calculation of oil saturation with current numerical simulation method has the disadvantages that the amount of calculation is large and calculation period is long, thus it is not suitable for rapid evaluation of remaining oil saturation distribution of oil layers. In order to solve this problem, a simple and easy method is presented to rapidly evaluate the distribution of remaining oil in waterflooding oilfield. It calculates oil saturation through analyzing areal distribution of water saturation around water injectors. This method is applied in calculation of the remaining oil saturation of the upper 1-1 layer in unit Ⅷ in Shuanghe oilfield. The calculation results are basically in accord with the numerical simulation results. |
