## DESIGN OF PARTIAL SIMILARITY MODELS AND THEIR EVALUATION METHOD IN WATER FLOODING PHYSICAL SIMULATION

• 摘要: 采用相似准数敏感性分析方法，对各局部相似模型中所放松相似准数的敏感性进行分析，得到应尽量减少放松的相似准数. 提出了定量评价局部相似模型优劣的影响系数，通过比较该影响系数的大小即可定量评价各局部相似模型.结果表明：水驱局部相似模型的精度不仅取决于所满足的相似准数的个数，还与相似准数的相对放松量有关.

Abstract: To quantitatively evaluate the partial similarity modelsof water flooding, a new numerical approach of sensitivity analysis isproposed for the sensitivity of the relaxed dimensionless parameter.The sensitivity factor quantifying the dominance degree of the relaxeddimensionless parameter is defined. By solving the dimensionless governingequations including all dimensionless parameters, the sensitivity factor ofeach relaxed dimensionless parameter is calculated for each partialsimilarity model, thus the dominance degree of the relaxed one is quantitativelydetermined. Based on the sensitivity analysis, the influence coefficientof thepartial similarity model is defined as a criterion to evaluate each partialsimilarity model. The partial similarity model with the smallestinfluence coefficient can be singled out. Results show that theprecision of the partialsimilarity model is not only determined by the number ofdimensionless parameters but also by the relative relaxation quantity.
