Automatic Matching of Parameters for Calculating Bounded Water Saturation in PORTN

Two different methods are used in PORTN for calculation of bounded water saturation when the porosity is over 20% and less than 20%,and it is difficult to select manually the interpretation parameters for rational calculation of the bounded water saturation.The method of automatic matching parameters for calculating of bounded water saturation can not only solve the difficult problem of matching of parameters,but also make the calculation results of bounded water saturation more reasonable.Digital processing results of well logging data from hundreds of wells indicated that this method is reasonable and the application results are good.
