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.
The advantages and disadvantages of the existing main gray clustering models are analyzed, and the mechanism of the gray clustering original models is demonstrated.Aiming at the deficiency of some gray clustering models, an improved gray clustering model --- gray programming clustering is proposed. Applying the gray programming clustering model to the hydrocarbon capment evaluation, a new method based on the gray clustering analysis for the cap layer quantitative evaluation is derived. This method is suitable for less data situations and is an objective and comprehensive quantitative assessment method. A total of 12 cover objects from 4 sets of mudstone in 3 major exploration areas in Qiongdongnan Basin were evaluated by using the new method of gray planning clustering caprock evaluation.The results of the evaluation and the discovery of oil and gas in Ya 13-1 gas field and Ya 21-1 Exploration results are consistent.
