摘　　要：仲自勉等。用模糊聚类分析技术识别储层．测井技术，１９９５，１９（１）：２８～３４利用霍其士－莱赫曼统计法，从测井资料中优选出５组最能反映储层特征的流体参数，如地层胶结指数、有效孔隙度与电阻率孔隙度比值等。根据所提取的５组参数，再用均值模糊聚类技术对辽河油田冷东地区１８口井进行储层综合流体识别；同时，在计算过程中对测井曲线作环境校正、畸变参数修复和重构。本方法对储层评价、储量计算、指导射孔等都具有很好的实用价值。Using Hodges-Lehmann Statistic Method, 5 groups of fluid parameters (e. g.formation consolidation exponent, ratio between effective porosity and resistivityporosity, etc. ) which are the most important ones in reservoir characterization,areextracted from log data. Based on the above 5 groups of parameters, ISODATAfuzzy cluster analysis technique has been used for 18 wells to identify the reservoirfluid in Lengdong area of Liaohe Oilfield. In the calculation process, environmentalcorrection, distortion parameter rebuilt and reconstruction have also been made.Field examples show that this technique is quite useful for reservoir evaluation,reserves calculation and perforation.
