Abstract：Hydrocarbon-bearing characteristics of geologic traps in Yakela area in northern Tarim Basin were predicted by comprehensively using gray relational grade,fuzzy clustering and neural network methods The prediction uses many parameters in oxidation-reducing potential,radioactive energy spectrum,seism,gravity-magnetis suvery in high accuracy,frequency spectrum induced-polarization,etc.Curvilinear gray relational grade can be extended to gray relational grade of curved surface so as to cope with areal data processing Having analysed the application prerequisites,conditions and effects of above three prediction methodswe can see that the com-prehensive application of some prediction methods and multiparameters may reduce the multiple solution of hydrocarbon prediction This comprehensive prediction technique has brought obvious geologic effect For instance,industrial oil and gas flows have been seen in Dalaoba area,and only a check is needed in Tuoku area.
