The application of grey systemtheory to reservoir evaluation is introduced. The hierarchical-cluster analysis is firstly adopted to select relatively independent evaluation parameters, and six parameters are selected out of ten parameters, including variation coefficient, shale content, effective thickness, oil saturation, porosity and permeability. And then correlation analysis of grey systemtheory is used to determine the weight coefficient of each parameter. Based on calculation of the indexes for comprehensive evaluation of reservoir, inflection-point method is adopted to determine the classifying thresholds for the comprehensive evaluation of reservoir, and then conduct comprehensive quantitative evaluation. Good evaluation effects have been achieved. There are mainly type I and II reservoir in northern Putaohua Oilfield, and type II and III reservoir in southern Putaohua Oilfield.
