Abstract

Water saturation is one of t he key parameters to evaluate hydrocarbon reservoir . Based on t he core analysis result s and the bound water saturation derived rom the nuclear magnetic resonance (NMR) test results for several wells of Triassic low resistivity reservoir in southern Tahe Oilfield , the comparison of the evaluation results of water saturation derived from Archie equation and Waxman-Smits model respectively is carried out . The result shows that using Waxman-Smits model to evaluate water saturation in this area is more advisable.

Key words： reservoir characteristics; influencing factors; sedimentary facies; diagenesis; Ordos Basin
