Abstract: Design optimization is an important part of seismic data acquisition system. The acquisition system optimization based on the cross correlating similarities in seismic data is a quantitative analysis method for using the existing production and experimental data to simulate and process various acquisition schemes, calculate scaling coefficient between result data and objective data, by which analyze the data quality, on the basis of production and test data. This method takes account of the relations among the data quality, optimized acquisition system and cost, thus reducing the errors caused by qualitative analysis, and providing better decision basis for acquisition system optimization as necessary
