With the characteristics of effectively improving the limitations of single attribute analysis and making the results of reservoir description more reliable, seismic attribute fusion technology has been widely used in attribute analysis for years. RGB blend method fits well with the attribute interpretation and reservoir identification for combining various information of different frequency together. In this paper, we introduce two methods to improve the visual effect of the RGB attribute with the purpose of analyzing the attribute better and identifying the reservoir more easily. The two methods are both based on the RGB attribute, but better than it in effect, which is proved by the real data. The participation of full-frequency attribute and the intensity compensation in HSI colour space may be the main reasons.
