Abstract：Along with the constant development of detecting seismic attributes techniques, the kinds of seismic attributes also increase continuously. In view of complex relationship between predicted targets and seismic attributes, the seismic attributes sensitive to (or most effective on,or most representative of) targets predicted are not completely identical in different work areas and different reservoirs. For that reason, it has to optimize the seismic attributes. Generally, the optimized processing means that using human experiences and mathematic algorithm to optimize the fewest numbers of composition of seismic attributes characterized by most sensitive to (or most effective on, or most representative of) solved problems. The authors considered that the optimum of seismic attributes should mainly include two parts:preprocessing of attributes and selection of at-tributes. The paper appreciated these two parts of contents separately, which gave a reference to the researchers who engaged in optimum of seismic attributes.
