选取两个效果指标,结合模糊C均值算法和组合赋权法实现难采储量的分类.首先基于效果指标运用模糊C均值算法自动搜索储量的最佳类别,再利用主客观赋权偏差最小的思想,构建组合赋权模型,确定属性指标的权重,并计算储量效益指标值,结合模糊C均值结果判别难采储量类别.最后以大庆某油田为实例,对其难采储量进行了分类,有效指导难采储量滚动开发决策.
Select two effect indexes, combine the fuzzy C-means algorithm and combination weight method to realize the classification of difficult-to-reclaim reserves.Firstly, based on the effect index, the fuzzy C-means algorithm is used to automatically search the best category of reserves, and then the idea of minimizing the subjective and objective weights , Build the portfolio weight model, determine the weight of the index, and calculate the index value of reserve benefit, and determine the category of hard-to-extract reserves by combining the results of fuzzy C-means.Finally, an oilfield in Daqing is used as an example to classify the difficult- Difficult to reclaim reserves and develop decision - making.
