在韩大匡、陈钦雷所著《油藏数值模拟基础》一书,关于IMPES方法的章节中,将传导系数定义为几何因子和流动系数的乘积:
F为几何因子,i-1/2处的F定义为
为流动系数,油相在i+1/2处的定义为_{i+\frac{1}{2}})
F为几何因子,i-1/2处的F定义为
为流动系数,油相在i+1/2处的定义为_{i+\frac{1}{2}})

在CMG油藏模拟软件中,TRANSI,TRANSJ,TRANSK为传导率乘机因子,其默认值为1.0。
Flow between grid blocks is proportional to a cross-sectional inter-block flow area, an averaged permeability value, and a divisor equal to the inter-block distance. These terms combine to form a transmissibility which is calculated in the simulator. Before it is used, a transmissibility multiplier, as set by a *TRANSI, *TRANSJ or *TRANSK keyword, is applied.
从以上描述可以看出,CMG油藏模拟软件中的传导率和第2部分的定义相似。
