摘要
该文通过对原油采收率影响因素的分析，用层次分析法选择了１７个显著性影响因素，利用多层结构方法（即ＧＭＤＨ方法）建立了新的计算原油采收率的数学模型。与其它经验公式相比，用该模型进行预测简单、易行，误差小。
After analysis of the factors influencing oil recovery, 17 dominant ones were selected through analytical hierarchy process. A mathematical model for calculating oil recovery was set up by using of group method of data handling. The results predicted by this model were satisfactory. Compared with other methods, this model is simple, accurate and easy to use, and the predicted results are satisfactory.
