To quantitatively evaluate the partial similarity models
of water flooding, a new numerical approach of sensitivity analysis is
proposed for the sensitivity of the relaxed dimensionless parameter.
The sensitivity factor quantifying the dominance degree of the relaxed
dimensionless parameter is defined. By solving the dimensionless governing
equations including all dimensionless parameters, the sensitivity factor of
each relaxed dimensionless parameter is calculated for each partial
similarity model, thus the dominance degree of the relaxed one is quantitatively
determined. Based on the sensitivity analysis, the influence coefficient
partial similarity model is defined as a criterion to evaluate each partial
similarity model. The partial similarity model with the smallest
influence coefficient can be singled out. Results show that the
precision of the partial
similarity model is not only determined by the number of
dimensionless parameters but also by the relative relaxation quantity.
