| 摘 要： | 总结了童氏"7.5"的计算方法,并指出各种方法的优缺点。从油水相对渗透率之比与含水饱和度的函数关系出发推导出一种新的计算童氏"7.5"的公式,该方法能够较好地适用于低渗透油藏。通过实例,证实该方法是行之有效的,对低渗透油藏注水开发具有重要的指导意义。

| Abstract: | Tong"s "7.5" calculation method are reviewed in this paper and points out the advantages and disadvantages of various methods.Start from the function relationship between the rate of oil and water relative permeability and water saturation, deduced a new calculation formula for Tong"s "7.5".This method can be well applied to low permeability reservoirs. Through the example, this method is reliable and for low permeability reservoir water flooding development is of important guiding significance. |

| Keywords: | low permeability reservoir Tong"s chat water saturation rate of recovery |
