摘要： 改进归一化处理方法、引入因素权重系数、优化距离幂指数并考虑因素间的交叉作用,定义了“广义”距离,利用“广义”距离对反距离加权方法进行改进,建立了一种新的基于改进型反距离加权的提高采收率潜力预测方法。结合均匀设计生成聚合物驱样本集,运用该方法对样本集提高采收率进行预测,并与反距离加权方法进行了对比。结果表明,该方法有效地减弱了反距离加权方法存在的“牛眼”现象,预测提高采收率结果可靠,精度较高。

Abstract: By improving the normalization method, introducing the factor weight coefficient, optimizing the distance power index and considering the factor interaction, the "general" distance is defined. Based on this, the inverse distance weighted (IDW) method is improved, by which a new potential prediction method for enhanced oil recovery (EOR) is established. Integrated with uniform design, the sample set of polymer flooding is obtained. The EOR of sample set is predicted and compared with IDW. The result indicates that with the improved IDW method, the "bovine eye" phenomenon of original IDW can be improved effectively, and the predicted EOR result is more precise and reliable.
