灰色规划聚类及其在油气盖层评价中的应用

分析了现有主要灰色聚类模型的优缺点,论证了灰色聚类原模型的机理.针对一些灰聚类模型的不足,提出了一种改进的灰聚类模型--灰色规划聚类.将灰色规划聚类模型应用于油气盖层评价,从而导出了基于灰聚类分析的盖层定量评价的新方法.该方法适用于较少数据的情形,是一种客观的综合定量评价方法.应用灰色规划聚类盖层评价新方法对琼东南盆地3个主要勘探区4套泥岩共12种盖层对象进行了评价.评价结果与崖13-1大气田和崖21-1发现油气显示等勘查结果相吻合.图1,表5,参13.

Grey clustering with programming and application of assessing the caprock of oil and gas

The excellent and defect of gray clustering models in existence were analyzed and the mechanism of the original model was demonstrated in the letterpress.In view of the problems of the models in existence,an improved gray clustering model called as gray clustering with programming was put forward.The new method of cap rock quantitative evaluating was accordingly brought forward based on gray clustering.This method is impersonal and the same with the case of few data.Applying this new method,it was evaluated that 12 cap rocks in three entries mostly prospecting section in the basin in the southeast of Hainan Provice.The evaluating results of cap rock by gray clustering model with programming are identical with the prospecting results at the cliff 13-1 and at the cliff 21-1.1fig.,5tabs.,13refs.
