| description | The invention provides a seismic attribute optimization method and device. The method comprises the steps that the sample data of seismic attributes to be optimized in seismic data are extracted; according to the sample data, the weight values of the seismic attributes to be optimized are calculated; and the weight values of the seismic attributes to be optimized are sorted. Quantitative analysis is carried out on the extracted weight data of the seismic attributes to be optimized. A mathematical method is used to calculate the weight values of the seismic attributes to be optimized. According to the size of the weight values, the seismic attributes with small weight values are removed. The seismic attributes with large weight values are kept as optimized seismic attributes. Compared with an expertise optimization method, a mathematical optimization method has more adequate theoretical proof, a more rigorous derivation process and a more accurate optimization result. |
