区块开发指标的模糊预测
|
摘要
本文第一次把模糊聚类分析与贴近度结合使用与区块开发指标的预测,取得了良好的效果,对油田开发研究做出了较大贡献。本文以胜利油田已开发区块的数据为基础,采用模糊聚类的方法,将同类油藏中已经开发的区块进行了分类,再计算出新的区块与各类中已开发区块之间的贴近度以表明其相似程度,再根据择近原则将新的区块归类,然后根据所属类中已开发区块的相关开发指标对新区块的开发指标进行了预测,取得了较精确的结果。
In this paper,it is the first time to apply fuzzy clustering analysis and approach degree to predict the indexes of block-wide,and it has gotten much better effect,and it is very significant to the development research of Oilfield.Based on the known data of Shengli Oilfield's block-wides which have been developed,those block-wides can be classified into several groups by using the fuzzy clustering analysis method.Then,computing the approach degree between new undeveloped block-wide and each group,according to the choose-nigh principle,the group which is the new undeveloped block-wide ought to be classified to can be ascertained.In the end,according to the production indexes of the developed block-wides in the same group,the production indexes of the new undeveloped block-wide can be predicted,and the precision can fulfill actual requirement.
