| Abstract: | The way of chart plotting of water injectivity permeability for extra-low permeability reser-voir is presented in this paper. Sub-layer's permeability is calculated by using the data of interval transit time andnatural gamma read from logging diagrarn for typical injection profiles. Then a final linear equation is obtained ina rectangular grid between the maximum permeability and the low limit of the permeability fOr detedrining thewater injectivity of sub-layers in an injection well. This chart is verified with a high coincidence rate. |
